FOIRE AUX QUESTIONS - KX-P1540 PANASONIC

Comment remplacer le ruban encreur du Panasonic KX-P1540 ?

Éteignez et débranchez l'imprimante. Ouvrez le capot avant. Retirez l'ancienne cartouche de ruban en tirant délicatement. Insérez la nouvelle cartouche (réf. KX-P1540RB) en alignant les ergots. Assurez-vous que le ruban est bien tendu et enroulé. Refermez le capot. Consultez la notice pour plus de détails.

Que faire en cas de bourrage papier ?

Mettez l'imprimante hors tension. Ouvrez le capot avant et retirez délicatement le papier coincé en tirant doucement dans le sens de l'impression. Vérifiez qu'il ne reste pas de morceaux de papier. Utilisez le levier de dégagement du tracteur si nécessaire. Refermez le capot et rallumez.

Mon imprimante n'imprime pas, que vérifier ?

Vérifiez que l'imprimante est sous tension et que le câble d'interface (parallèle ou série) est correctement connecté. Assurez-vous que le ruban est en place et non usé. Vérifiez les paramètres du pilote d'impression (port, type d'imprimante). Testez avec une page d'autotest (bouton LF/FF).

Comment effectuer un autotest sur la KX-P1540 ?

Mettez l'imprimante hors tension. Maintenez enfoncé le bouton LINE tout en remettant l'imprimante sous tension. Relâchez le bouton. L'imprimante imprime une page de test listant les jeux de caractères et les réglages. Pour arrêter, mettez hors tension.

Quel type de papier puis-je utiliser ?

L'imprimante accepte du papier feuille à feuille (A4, lettre) et du papier continu (formulaires). Utilisez du papier de 60 à 90 g/m². Les enveloppes et les étiquettes sont possibles avec les réglages appropriés. Évitez le papier trop épais ou enduit.

Comment régler l'épaisseur du papier pour les formulaires carbone ?

Utilisez le levier de réglage de l'épaisseur (paper thickness lever) situé sur le côté de l'imprimante. Tournez-le pour l'adapter au nombre de copies (original + copies). Pour 1+3 copies, réglez la position 4. Consultez la notice pour les positions exactes.

Où trouver le pilote d'impression pour Windows 10 ?

Panasonic ne fournit plus de pilotes spécifiques. Utilisez le pilote générique 'Imprimante matricielle' de Windows ou le pilote 'Panasonic KX-P1500' compatible. Vous pouvez aussi utiliser le mode émulation Epson FX-80. Téléchargez les pilotes sur le site de Panasonic ou utilisez ceux fournis sur des CD.

Comment passer en mode silencieux ?

Le mode silencieux réduit le bruit en ralentissant l'impression. Appuyez sur le bouton SILENT (ou SILENCE) du panneau avant. Un voyant s'allume. Pour désactiver, appuyez à nouveau. Ce mode est utile pour les environnements calmes.

Ma tête d'impression semble sauter des points, que faire ?

Cela peut indiquer une aiguille coincée ou un ruban usé. Nettoyez la tête avec le kit de nettoyage (tête d'impression) : appliquez quelques gouttes de solvant sur la mousse et imprimez un motif de nettoyage. Remplacez le ruban si nécessaire. Si le problème persiste, la tête peut être endommagée.

Comment connecter l'imprimante en série RS-232C ?

Utilisez un câble série RS-232C mâle/femelle. Configurez les paramètres de communication (baud rate, bits de données, parité) via les commutateurs DIP à l'arrière de l'imprimante.

1. Introduction

1.1 Product Overview

This printer is a high quality impact dot matrix printer designed for use with a wide variety of computers in a business environment. This printer can also be used to provide a printout from computer terminals connected to a network.

This printer is rated at 240 characters per second (cps) and can print bi-directionally, i.e., left-to-right and right-to-left. As standard, the printer has three basic print fonts—Draft, Text and Letter Quality. Additionally, external Letter Quality fonts are available by using optional font cards. It also has 6 character pitch selections. They are 10, 12, 15, 17 & 20 characters per inch (cpi) and proportional spacing (ps). These modes can be selected by front panel switches or through software commands. This printer also has a graphics mode. In this mode the user can create charts, graphs or other illustrations.

This printer uses a 24 pin print head to form a 24×9 dot matrix character in draft and text modes. In letter quality mode, the matrix is 24×30. The standard character set consists of 96 ASCII characters which can be printed in conventional font or in italics. You can also select 10 international character sets.

Tractor feed and friction feed are both standard on this printer. This allows the printer to accommodate both fanfold and single sheet paper as well as envelopes. The unidirectional tractor option allows paper to be fed from beneath the printer.

Also, the printer uses "push" tractors. Therefore, continuous forms can be torn off without the need to skip a form when advancing to the next one. The printer also has a forms length selector on the front panel. The user can select the length of the form between 3" (76 mm) and 14" (356 mm). This is very useful when printing on non-standard paper sizes such as mailing labels.

The printer head life is designed for 200 million dots per pin. The seamless fabric ribbon has an operating life of 3 million characters. The ribbon cassette design makes changing the ribbon easy and clean.

This printer has both Centronics parallel and RS-232-C serial interface as standard. The RS-232-C interface supports the XON/XOFF and DTR handshaking protocols at baud rates up to 9600 bps. The printer also comes equipped with an internal standard 13.5K buffer. An additional 32K buffer is available as an option. This expands the total buffer size to 45.5K. With this option the buffer or a portion of it can be used as a receiving buffer or a portion of it can be used as a download font area. The buffer area assignment is selected by DIP switches.

For software compatibility, this printer has three command sets—Epson LQ-1500™, IBM Proprinter™ and Diablo® 630. Each set can be selected by setting corresponding printer mode with DIP switch 1-1 and 1-2. Refer to DIP switch section in this manual.

2.4 DIP Switches

DIP switches allow the user to set certain operating conditions of the printer. The switches are read into memory on power up. These memory locations then contain an image of the switch settings. The computer can change the contents of the memory and thereby effectively change the switch settings. Character sets, skip perforation etc. can be changed in this manner. Refer to sections 6, 7 and 8 for information regarding software control of the switches. Figure 2.6 shows the location of the DIP switches at the rear of the printer. Table 2.8 lists the settings of switch banks SW1, SW2 and SW3.

2.5 Paper Installation

The paper feed mechanism can handle single sheet paper and envelope or fanfold paper. Alternating between the two is accomplished by using the lever on the left side of the printer labeled "F" (friction) and "T" (tractor). In the friction mode the paper is held by pinch rollers which press the paper against the platen. This mode is used for single sheets and envelopes. The tractor mode is for use with fanfold paper. This printer uses push-type tractors. This allows continuous forms to be torn off without wasting a copy between printouts. Refer to following paper installing procedures.

Figure 2.7A Paper Feed Selector

Figure 2.7B Inserting a Single Sheet

Figure 2.7C Aligning a Single Sheet

Single Sheet and Envelopes

To install a single sheet of paper or envelopes, follow these procedures.

• Turn the power switch ON. A one second beep will sound.

• Place the PAPER FEED selector in the "F" position. Refer to Figure 2.7A.

• Raise the top cover and insert the paper behind the platen as Figure 2.7B shows. Use the markings and paper guide on the top cover as a guide.

• Pull the paper bail release lever toward the front of the printer to wrap the paper automatically around the platen. Then push it back into its original position.
• Press down and hold the line feed switch (LF) to advance the paper.
• To align the paper horizontally or vertically, set the paper feed selector to the "T" position. This releases the pinch rollers and allows the paper to be positioned as required.
• Set the selector back to "F" before printing.

- Refer to Figure 2.8B. Unlock the tractors by pulling forward on the tractor clamping levers.

- Slide the tractors out toward the sides and raise the covers.

- Place the paper feed selector in the "T" position.

- Align 4-5 paper sprocket holes with tractor pins and close tractor covers.

- Center the paper horizontally without any slack, using the scale on the scale plate as a guide. The printer will print between 0 and 136 on the scale (PICA).

- Press back on the tractor clamping levers locking the tractors in place.

- Pull the paper bail release lever toward you to advance the paper.

- Push the paper bail release lever toward the platen.

- Visually insure the tractor pins are in the center of the paper sprocket holes.

- Press down and hold the line feed switch (LF) to advance the paper.

- Rotate the platen knob in the reverse direction to adjust printing position.

- Replace the top cover as shown in Figure 2.8C. Note: Position four bail rollers at the same intervals on the paper.

Stacking fanfold paper

To insure smooth paper flow when using fanfold paper, be sure the paper is not stacked higher than the paper separator. By feeding the paper as shown in Figure 2.9, the weight of the paper will provide reverse tension. The paper should be directly behind the printer and not off to one side.

Figure 2.10 Adjusting the Head Gap

Table 2.9 Head Gap Adjustment

Figure 2.11 Power Switch

2.6 Adjusting the printing head gap

The distance between the printing head and platen can be adjusted to compensate for the thickness of the paper.

Figure 2.10 shows the location of the head gap lever.

The 6-position head gap lever moves the print head closer to or farther away from the platen approximately 0.0028 inch (0.07 mm) per step. To avoid the possibility of print head or ribbon damage, the head gap lever should always be set to the upper position (-) when printing on single sheet paper. For thick paper or multi-part forms, move the lever toward the lower position (+). Maximum paper thickness is 0.013 inch (0.32 mm).

Note:

When the printer is shipped the head gap lever is set to the lower position (+).

2.7 Power Up

The power switch is located on the left side of the printer toward the rear as shown in Figure 2.11. It is used to turn the AC power ON or OFF. When the power is supplied to the printer the power indicator light on the front panel will light.

The following procedures should be followed when turning the printer on:

1. Insure that the printer carriage stopper has been removed.
2. Load the paper and set the paper feed selector in the proper position.
3. Be sure the ribbon is installed correctly.
4. Set the DIP switches as required.
5. Turn the power switch off and plug the power cord into an outlet of the proper rating.
6. Turn the power on.

2.8 Aligning the top of form

This printer has a line counter which keeps track of the vertical position of the print head. Each time power is turned on the line counter is reset and the current position of the head is designated as line one. This location is referred to as TOP OF FORM. A page is defined by the page length designation command. The first line of text will begin 13 " (8.5 mm) from the top edge of the back tension plate. Refer to the Figure 2.12.

2.9 Self Test

The printer has a self test feature which allows the user to test the printer independently. The mode is entered by turning on the power switch while pressing the line feed (LF) switch. All 96 ASCII characters will be printed continuously until the power is turned off. The FONT and PITCH selector switches are active in self test. Even though the printer is in the Pgm mode when power is turned on, other modes can be tested by pressing the FONT and the PITCH Selector Switches. The self test will stop automatically in approximately 15 minutes (with draft character printing). To release the self test mode turn the power off.

2.10 Connecting to Computer

The printer communicates with the computer through a parallel interface cable or a serial interface cable. The printer has both Centronics and RS-232-C serial interfaces as standard. The user needs an interface cable to connect the printer to the computer.

See Section 9 "Interfaces" for detailed information.

Table 3.1 Panel Switch Alternate Function

3.1 Front Panel Switches

ON LINE switch

The ON LINE switch is an alternate action switch which opens and closes the communications line with the computer. When the power switch is turned on, the printer will power up in the ON LINE mode if paper is installed and the smoked plastic cover is closed. If paper is not installed or the smoked plastic cover is opened, the printer will power up in the OFF LINE mode. The printer can be switched between the ON LINE and OFF LINE modes by pressing the ON LINE switch.

If the printer is in the ON LINE mode and a paper out condition occurs, or the smoked plastic cover is raised, or the ON LINE switch is pressed, the printer will switch to the OFF LINE mode and the indicator light will be out.

In the ON LINE mode, the printer is able to receive information from the computer and the ON LINE indicator will be lit. When OFF LINE, the indicator light will be out and the printer can no longer receive data.

This switch is also used to allow loading a single sheet when the FUNCTION switch is pressed.

FUNCTION switch

This switch is an alternate switch and used in conjunction with the front panel switches to give them new functions. When this switch is activated the ON LINE indicator starts blinking. In this mode the front panel switches have new functions as shown in Table 3.1.

Press the switch to return to normal mode.

See Section 3.2 "Function Mode" for detailed information.

Table 3.2 FONT Selection

LF (Line Feed) switch

This switch is active in the OFF LINE mode and when the printer is not printing in the ON LINE mode. Pressing this switch will cause the paper to advance one line. Multiple line feeds can be performed by holding the switch down. The print head is in the skip perforation area, the paper will advance to the top of the next page.

This switch moves the carriage toward right when the FUNCTION switch is pressed.

FF (Form Feed) switch

This switch is active in the OFF LINE mode and when the printer is not printing in the ON LINE mode. Pressing the FF switch will advance the paper from its current location to the top of the next page. Then a new top of form is established. The FF switch is not active in a paper out condition.

This switch is used to move the carriage toward left when the FUNCTION switch is pressed.

FONT selector switch

The FONT selector switch allows the user to choose among print styles. The light on the front panel indicates the current print font. The default condition (the mode selected when power is turned on) is DRAFT. When the switch is pressed the print font will advance to the next position. Table 3.2 shows the status of the lights for each font. The printer has three basic print fonts- Draft, Text and Letter Quality (LQ). When an optional font card is installed in the printer, an external font is available by selecting CARD. If an optional font card is not installed, L2 and L3 indicators bllnk continuously. When the LQ DLL is selected, letter quality download characters are printed. Font selections through software commands can be made only when the printer is in Pgm (DRAFT, 10 cpi) mode. The indicator lights will not change when the mode is changed through software commands.

The FONT selector switch is used to set a right margin position when the FUNCTION switch is pressed.

Table 3.3 PITCH Selection

Figure 3.5 FORM LENGTH Switch

PITCH selector switch

This printer has 5 character pitch selections. They are 10, 12, 15 & 17 characters per inch (cpi) and proportional spacing (PS). The PITCH selector switch allows the user to change these character pitches. The light on the front panel indicates the current character pitch. The default condition (the pitch selected when the power is turned on) is 10 cpi. When the switch is pressed the pitch will advance to the next position. Proportional spacing is effective only for letter quality fonts. When the FONT selector switch is set DRAFT or TEXT, L5 and L6 indicators blink continuously. Table 3.3 shows the status of the lights for each character pitch. In 12 HS mode characters will be printed in 12 cpi at 20 percent higher speed.

The PITCH selector switch is also used to set a left margin position when the FUNCTION switch is pressed.

Note: Pitch selections through software commands can be made only while the printer is in Pgm (DRAFT, 10 cpi) mode. The indicator lights will not change when the mode is changed through software commands.

20 cpi mode can be selected only through software commands.

FORM LENGTH selector switch

The form length selector switch sets the form length in inches. The setting of the switch is sensed automatically when the power is turned on or when the switch setting is changed. A new top of form position is set each time the form length is changed, either through the form length software command or by changing the switch setting.

3.2 Function Mode

Memo Load

This printer can use single sheet, envelopes and fanfold paper. When you use single sheet or envelopes without removing the fanfold paper:

1. First, tear off the printed pages of the fanfold paper.
2. Turn the power on and press the FUNCTION switch. The ON LINE indicator will start blinking. This indicates the printer is in the function mode.
3. Press the ON LINE switch. The fanfold paper will go back halfway and stop. The ON LINE indicator will stop blinking and the printer automatically goes back to normal mode.
4. Move the paper feed selector to "F" position.
5. Raise the top cover and insert a single sheet.
6. Move paper bail release lever toward the front of the printer to wrap the paper automatically around the platen. Then push it back to its original position.

Now you can print on the single sheet.

When printing on the single sheet is done, remove it by rotating the platen knob. Then move the paper feed selector to "T" position and pull the paper bail lever toward you to advance the fanfold paper to print start position.

Margin Control

Left and right margins can be set not only through software commands but also using the front panel switches. Use the following procedure:

1. First turn the power on and press FUNCTION switch on the front panel. The ON LINE indicator will start blinking. This means the printer is in the function mode. In the function mode each front panel switch has the following function:

Panel switch Function

LF	Moves carriage to right.
FF	Moves carriage to left.
PITCH	Sets left margin position.
FONT	Sets right margin position.

1. Press and hold down LF or FF switch to move the carriage to a desired left (or right) margin position.
2. Press the PITCH or FONT selector switch to set left (or right) margin.
3. After setting left and right margins press the FUNCTION switch to return the printer to normal mode. The ON LINE indicator will stop blinking.

Note:

1. You can set either left or right margin first.

2. In the function mode, when moving the carriage by using LF and FF switches, if the carriage reaches an end of the platen the carriage will move rapidly to opposite side. This is helpful in moving the carriage to the second margin position when the first is far from it.

3.3 Print Feature Control

Print Quality and Font

This printer has a wide variety of print capabilities as shown below. The user can select any print mode by combining them.

Quality	Font	Pitch	Highlight
Draft		10	Double width
Text		12	Emphasize
Letter Quality	Courier	15	Double strike
	Option Font	17	Underline
	Superscript	20*	Overline
	Subscript	PS	(IBM)
	Italic	12HS	Bold, Shadow (Diablo 630)

*20 cpi mode is available only in Epson LQ-1500 mode.

This printer has three print quality levels: Draft, Text and Letter Quality. You can select any level for your needs. Draft is printed at the fastest speed and is normally used for printing draft documents. Letter Quality produces the best print quality; it is used to print the final version of formal documents. The printer has two kinds of letter quality fonts. They are internal letter quality font (Courier) and external letter quality fonts which are supplied as optional font cards.

Super/subscript font characters are two thirds the height of normal characters and are typically used in mathematical expressions, chemical formulae, and footnoting.

Each print quality mode allows a wide variety of output by mixing character pitches and highlighting by the PITCH selector switch on the front panel or through software commands.

Character Pitch

This printer has 7 character pitches: 10 cpi (Pica), 12 cpi (Elite), 15 cpi (Micron), 17 cpi (Compressed), 20 cpi (Elite compressed), 12 cpi High Speed (HS) and Proportional Spacing. Each character pitch gives the same height but different horizontal dot pitches to characters. In proportional spacing, the spacing of each character varies. For example, an "I" will take up less space than an "M" or a "W". Proportional printing gives the document a typeset appearance. Letter quality font can be printed in proportional spacing, draft and text fonts, however, cannot. In 12 cpi HS, draft characters are printed at a higher speed (240 cps) than normal (200 cps) in elite pitch, text characters are printed at a higher speed (160 cps) than normal (133 cps) and letter quality characters are printed at a higher speed (80 cps) than normal (67 cps) in elite pitch. 20 cpi mode is available only in Epson LQ-1500 mode.

Character Highlighting

This printer allows a document a wide variety of print styles by mixing fonts and pitches.

Double width printing makes the width of a character twice that of normal one.

Double printing uses a double strike with two passes of the print head, feeding the paper 1/180" (0.14 mm) between the first and second pass.

Emphasized printing makes two passes of print head, the second strike is performed slightly to the right of the first.

Diablo 630 mode, bold printing prints on the same location twice, and shadow printing makes two passes of the print head, the second strike is performed 1/120" (0.21 mm) to the right of the first.

Underline printing produces continuous line under characters, using 24th pin of the print head.

IBM Proprinter mode has overline printing which uses the first pin of the print head.

Front panel switch control

This printer has FONT and character PITCH control switches on the front panel. If your packaged software does not provide print quality or size commands, these switches provide an easy way of doing so. Setting the FONT switch to letter quality (LQ) for example, allows the printing of a draft document in letter quality without any software change. The FONT switch offers five choices, the PITCH switch offers six.

Setting the FONT and PITCH switches to any combination other than DRAFT and 10 cpi overrides any software commands addressing these functions. To allow software to control font and pitch, you must have the FONT switch set to DRAFT and the PITCH switch set to 10 cpi.

Font Card Option

This printer has 7 LQ font card options—Bold PS, Roman, Prestige, Sans Serif, Orator, Script and OCR-B. Ask your dealer for availability.

Installation

Technical line drawing of a mechanical component with directional arrows indicating motion (no text or symbols)

Figure 3.6 Installing the Font Card

• Before inserting or removing the font card, the power of the printer must be turned off.
• Gently insert or remove the font card into or from the printer.
• When inserting, push the font card until it stops with a click.

Operation

- Set the FONT selector switch on the front panel to "CARD" when you print your document with LQ font contained in the font card.

Caution

• Keep the font card in its protective cover when it is not installed in the printer.
• Keep the font card from direct sunlight or high temperature.
• Do not bend or subject the font card to strong shocks.
• Keep the font card away from water or other liquids.
• Do not touch the font card's connector.

3.4 Detectors

Out of paper detector

This printer has two paper out detectors. One is located under the platen. The other is located at the bottom and used only with the bottom feed tractor option. They sense the absence of paper. When an out of paper condition occurs, the printing stops, the printer goes to the OFF LINE mode, and the alarm sounds, and the Paper Out light is lit. To continue printing to the end of current page when out of paper condition occurs, press the ON LINE switch. To resume printing after paper out condition, install the paper and press the ON LINE switch. The printer will start printing.

The Paper Out detector will be disabled under the following conditions:

●The paper feed selector is set to friction feed.
●DIP switch SW1-8 is ON.
- The paper out detector is disabled by a software command.
●The smoked plastic cover is open.

Over heat detector

If the printer is printing continuously for extended periods of time, the printhead may become overheated. When this occurs, an internal protective circuit will cause the printer to quit printing and the alarm will sound at one second intervals. This condition will remain in effect until the head temperature decreases sufficiently, at which time the printer will automatically resume printing.

Cover open detector

When the smoked plastic cover is opened, the printer detects it and goes to the OFF LINE mode after printing to the end of the current line. The print head moves to the auto paper loading position and sounds the alarm five times. When the ON LINE switch is pressed after closing the cover, the print head returns to the home position, and the printer starts printing.

3.5 Initialization

The printer is initialized under the following conditions:

-The AC power is turned on
-The PRIME signal is received
-The RESET command is received

When the printer is initialized, the following conditions are set:

-The print head goes to the home position
-The print buffer is cleared
-The receive buffer is cleared (not cleared by RESET PRINTER command)
-Vertical tab settings are cleared
-Horizontal tabs are set every 8 columns (Epson/IBM Printer mode)
-Horizontal tabs are cleared (Diablo 630 mode) -The DIP switches are read and printer modes set
-Print mode is set to Pgm by power on
-Print mode set by selector switch is not changed by PRIME signal, RESET PRINTER command*
-Present form position is designated as top of form
-All modes set by control and escape commands will be cleared
-The printer goes ON LINE
-The form length is set according to the position of the form length selector switch
The download character buffer is cleared (not cleared by PRIME signal in IBM Proprinter mode)
*Some software packages send PRIME signal at the beginning of their programs. Print modes set by the selector switch will not change.

3.6 Hex. Dump

The HEX. DUMP mode is activated by turning on the power while pressing both the line feed (LF) and form feed (FF) switches. In this mode, all data received from the computer is printed in hex. code instead of the normal ASCII characters. Function codes for the printer (CR, LF, HT, etc.) are not executed. To reset the mode, turn the power off, then back on.

4. Software Introduction

4.1 Introduction

In order for a computer to communicate with a printer, both pieces of equipment must understand a common language or coding scheme. One such coding scheme is called ASCII (American Standard Code for Information Interchange). As an example, the ASCII code for the character "K" can be expressed in any of the following forms:

(01001011) _2 —Binary

4B HEX1 4B _H —Hexadecimal

75 DEC, 75—Decimal

Many computers allow you to enter ASCII codes in hexadecimal form. Most computers which support ASCII allow the input to be in decimal form. Many allow you to enter the code in either form. Once entered, the ASCII codes are converted to binary form by the computer and then sent to the printer.

In the sections which follow, you will see how to enter various ASCII codes to enable the printer to perform the functions you would like. Since the decimal equivalent of the ASCII code is most commonly used, all examples which follow will use the decimal form.

Appendix A contains the ASCII character and control command tables used by this printer.

4.2 Control Codes

The various printer functions are set through the use of control codes, which consist of one or more ASCII characters entered into the computer in a special way. These control codes often differ from printer to printer. Control codes generally fall into two categories: one-byte control codes and multi-byte control codes. The multi-byte control codes are often referred to as Escape Sequences since each code begins with the ASCII code for the ESCAPE character (ESC). Such an ESC character should not be confused with the Escape Key found on some computer keyboards.

Control codes can be sent to this printer from your computer in different ways. The three most common ways are:

●Through commercial software packages
- Directly from the keyboard
●From within a user-written program

The latter two methods will specifically reference the BASIC language, although other languages such as FORTRAN, PASCAL, etc., can also be used. We will use BASIC since it is relatively easy language to use. In addition it is the most commonly used microcomputer language.

4.3 Entering Control Codes through Commercial Software Packages

Many computer users do not have the time, the expertise, or the interest to develop software suited for their applications. In such cases software written by professionals can be purchased. Such software should be selected not only to meet the needs of the user, but must also be compatible with both computer and printer.

Commercial software is often written with what is called a driver. A driver is that part of the software which allows the user to configure the package to the type of printer and interface being used. Once the software has been booted, the user is generally requested to supply additional information such as:

• Brand/Model of printer being used.
• Slot number in which interface card is installed.
• Baud rate, parity, etc. if a serial interface is being used.

Once the necessary information has been supplied, the software will provide the computer with the control codes and other data needed by this printer.

Many word processing packages will request that you enter the ASCII codes used by this printer for special settings such as underlining, compressed print, super- and subscript, italics, etc.. In all cases you should refer to your software instruction manual for the proper use of the package with this printer.

4.4 Entering Control Codes Directly from the Keyboard

With many computers, the BASIC language is ready to use once you power up. With others, BASIC must be loaded from cassette or disk. In any case, once BASIC is ready, you may then enter these printer control commands directly from your computer keyboard.

BASIC requires the use of the PRINT command (or LPRINT, PRINT#, etc. depending on the type of BASIC your computer uses) to process and send the control commands to this printer. As part of this PRINT command, you must supply the appropriate ASCII code(s) for the CHR\$ function.

For example, the command: LPRINT CHR\$(15) followed by a RETURN will set this printer to compressed mode. Subsequent output to this printer will appear in compressed mode.

If, after issuing the above command, subsequent PRINT statements output nothing to the printer, check for one or more of the following:

• Have you indicated to the computer that output is to the printer and not the screen? For example, PR#1, say, causes subsequent PRINT statements on the Apple® computer to PRINT the printer and not the screen. LPRINT does the same in Microsoft® BASIC.
• Is this printer on line? If not, press the green ON LINE button on the front panel.
• Is the interface cable plugged into the computer and printer?
• When using a serial interface, is the baud rate setting on the printer the same as that on the computer or interface card?

Notice that when you enter a BASIC command directly from the keyboard, you do NOT use a line number as you would in a BASIC program. Moreover, control codes may be entered only one line at a time.

4.5 Entering Control Codes from Within a Program

Control commands may also be entered from within a BASIC program. The advantage to this technique is that you can incorporate a number of different control commands into a single program and therefore produce output with a variety of special features. This is done by RUNning your program once. In this case BASIC requires that each line in your program be preceded by a line number.

As an example, we mentioned earlier that the command LPRINT CHR\$(15) entered directly from the keyboard will set compressed print on this printer. From within a BASIC program, this command might be:

50 LPRINT CHR\$(15)

The following chapters will show you how to enter each of the control commands which this printer uses.

4.6 Entering Hexadecimal Code

In the event that you will be entering ASCII codes in hexadecimal form, you must supply two extra characters per code. These are the ampersand (&) and the letter H. The example below illustrates the BASIC command to set compressed print on this printer.

Decimal	Hexadecimal
LPRINT CHR(15)	LPRINT CHR(&H0F)

Refer to Appendix A for the ASCII code table.

4.7 Control Codes

A number of the printer control commands require only a single ASCII-coded character as part of the LPRINT statement. The command LPRINT CHR\$(15) which we discussed earlier is an example of a single-byte control command.

Multi-byte control codes, often called Escape control codes or Escape sequences, always begin with an ESC designation. ESC is designated by CHR\(27) in decimal form or CHR\(&H1B) in hexadecimal form. The ESC designation is always followed by one or more additional codes, hence, the name multi-byte control code.

In BASIC, these two or more bytes are joined (or concatenated) into a single command or string using either a plus (+) sign, a semicolon (;), or by neither symbol but rather by listing one byte after another without any spaces. BASIC on many computers allows you to use any of these formats. Refer to your BASIC manual for the proper method of string concatenation.

Table 4.1 shows equivalent methods of entering multi-byte control commands for most computers.

There is one remaining input format commonly used to reduce the keystrokes necessary to enter a multi-byte control command. As you examine the multi-byte control commands in the pages ahead, you will notice that the second byte, with the exception of ESC+SO and ESC+S1, is always a character which appears somewhere on your keyboard. In such cases, rather than enter that character's ASCII code as part of the CHR\$ function, you may simply enter that character in quotes ("). For example, to set pica pitch (ESC+P), you may enter:

LPRINT CHR\(27)+CHR\(80);

or

LPRINT CHR\$(27) + "P";

As another example, to set double width printing, you may enter:

LPRINT CHR\(27)+CHR\(87)+CHR\$(1);

or

LPRINT CHR\(27) + "W" + CHR\(1);

With this method, any of the three input formats shown in Table 4.1 may also be used (subject to the BASIC you are using).

This printer has three printer modes. They are Epson LQ-1500, IBM Proprinter and Diablo 630 mode.

Software commands of each mode are covered in the corresponding chapter.

Table 4.1 Input Formats

5.1 Down Line Load Characters

If the printer does not contain all the characters you need, with the 32 K byte option you can custom design and load up to 18 K bytes of characters. Draft and letter quality fonts are downloadable simultaneously. Draft download characters are printed when the printer is in draft mode; LQ characters are printed when it is in LQ mode.

Note: Down line load command in IBM Proprinter mode does not have compatibility with IBM Proprinter.

Making Maximum use of the buffer

The 18 K (18, 432) bytes available can be divided between draft and letter quality characters in any combination, subject to hexadecimal address and buffer limits. Draft letters require 30 bytes each while LQ letters require 114. To determine if the desired combination will fit, use the formula:

(# of draft characters×30)+(# of LQ characters×114)≤18,432

For example: 128 draft and 128 letter quality are desired.

(128×30)+(128×114)=3,840+14,592=18,432, therefore this combination will fit.

Because no more than 256 addresses can be identified in 1 byte (00 HEX -FF HEX ), 256 is the maximum of draft characters that can be defined. The maximum number of LQ characters that can be loaded is 161.

Defining Down Line Load Characters

1. Draft Font

To download a character, you must first design the character. A draft font download character uses 9 columns and 24 rows of dots. Since a given column contains 24 dots, each column is divided into 3 portions, upper 8, middle 8 and lower 8 dots. Column 1 is labeled P_1H for the upper 8 dots, P_1M for the middle 8 dots and P_1L for the lower 8 dots. Similarly column 9 is labeled P_9H for the upper 8 dots, P_9M for the middle 8 and P_9L for the lower 8 dots. Columns 10, 11 and 12 are always set to zero, thus we are working with P_1H through P_9L . In the matrix below, the circles represent pins which may be fired. You may darken any circle provided no two adjacent horizontal circles are filled in. Once you have designed the character, you must quantify each dot column, P_1H-P_9H , by summing the powers of two represented by each dot. Consider the design of the Greek character gamma.

$$ \begin{array}{l} P _ {1 H} = 0 \ P _ {1 M} = 2 ^ {7} = 1 2 8 \ P _ {1 L} = 0 \ P _ {2 H} = 2 ^ {0} = 1 \ P _ {2 M} = 0 \ P _ {2 L} = 0 \ P _ {3 H} = 0 \ P _ {3 M} = 2 ^ {7} = 1 2 8 \ P _ {3 L} = 0 \end{array} $$

$$ \begin{array}{l} \mathrm {P_ {4H}} = 0 \ \mathrm {P_ {4M}} = 2 ^ {6} + 2 ^ {0} = 6 5 \ \mathrm {P_ {4L}} = 2 ^ {6} = 6 4 \ \mathrm {P_ {5H}} = 0 \ \mathrm {P_ {5M}} = 2 ^ {4} + 2 ^ {1} = 1 8 \ \mathrm {P_ {5L}} = 2 ^ {4} = 1 6 \ \mathrm {P_ {6H}} = 0 \ \mathrm {P_ {6M}} = 2 ^ {2} + 2 ^ {0} = 5 \ \mathrm {P_ {6L}} = 2 ^ {6} = 6 4 \end{array} $$

$$ \begin{array}{l} \mathrm{P} _ {7 \mathrm{H}} = 0 \ \mathrm{P} _ {7 \mathrm{M}} = 2 ^ {4} = 1 6 \ \mathrm{P} _ {7 \mathrm{L}} = 0 \ \mathrm{P} _ {8 \mathrm{H}} = 2 ^ {0} = 1 \ \mathrm{P} _ {8 \mathrm{M}} = 2 ^ {6} = 6 4 \ \mathrm{P} _ {8 \mathrm{L}} = 0 \ \mathrm{P} _ {9 \mathrm{H}} = 0 \ \mathrm{P} _ {9 \mathrm{M}} = 0 \ \mathrm{P} _ {9 \mathrm{L}} = 0 \end{array} $$

Input format for download command is:

Program line 20 is necessary for downloading draft font and designates draft printing.

Next you determine where in RAM the character(s) should be stored. The variables "n" and "m" are used for this purpose. The value specified for "n" indicates the location into which the first download character will be stored. If you are storing a single character, then n=m.

We must next define the value of “ d_0 ”, “ d_1 ” and “ d_2 ” which specifies attribute information. The attribute information includes the following:

d_0= number of space dot columns to the left of the character body d_1= number of character body dot columns d_2= number of space dot columns to the right of the character body

In our sample program, we create gamma character. This character consists of no left space dot columns, 8 body dot columns and 4 right space dot columns 9, 10, 11, 12. Therefore,

d_c=0, d_1=8 and d_2=4.

The combinations of d_0 , d_1 and d_2 are as follows:

	d_1 (Maximum)	d_0+d_1+d_2
Draft	9	12
LQ	37	—

The number of printable dots for characters downloaded in the letter quality font is as follows:

	d_0+d_1+d_2
LQ 10 cpi	36
LQ 12 cpi	30
Proportional Spacing	—

Program lines 40–80, therefore, use the eight values P_1H-P_8L to define the shape and size of gamma.

Note: Although two horizontal adjacent columns cannot be printed in draft and letter quality printing mode, in text printing mode any dot position can be printed.

Program line 100 selects download character generator. After this selection, by printing the download code (in this example, CHR\$(65)="A") downloadable font is printed.

Designing and storing fonts can be performed in the same way as with draft fonts. Here, only a sample is shown as follows:

5.2 Bit Image (Graphics)

Bit image (Graphics) is used to produce pictures, graphs, charts or creative patterns. Many commercial software packages use bit images. This printer has six 8-pin bit image modes and five 24-pin bit image modes, so that it can provide you with a wide variety of image printing. When you use a commercial software package you should refer to your software instruction manual for the proper use of it with this printer. Each printer mode has its own bit image commands. Although there are small differences among them, LQ-1500 printer mode is used here as an example of how to print bit images through software commands.

Dot Density

Dot density (dot resolution) refers to the maximum number of dots which can be printed in an inch or on a line. This printer enables you to access a variety of dot densities through specific control commands. The various dot densities and corresponding control commands appear in Table 5.1.

Command	Function	Dots/inch	Dots/line
ESC + K + n_1 + n_2	Standard density	60	816
ESC + L + n_1 + n_2	Double density	120	1632
ESC + Y + n_1 + n_2	Double speed, Double density	120	1632

Table 5.1 Dot Density

8-Pin Bit Image Mode

This printer has 24 pins in the print head. The distance between the centers of adjacent pins is 1180'' (0.14 mm) and the diameter of each pin is 1127'' (0.2 mm). In 8-pin bit image mode the 24 pins of the print head are grouped into eight pin-blocks of three pins each (pin-block 8 is at the bottom, pin-block 1 is at the top). One byte is sent to the printer for each column to be printed. Each bit of that byte represents an individual pin-block. By summing the powers of two corresponding to each pin-block you wish to fire, you will obtain a numerical value for the column in question. By sending a string of bytes, numerical values for each column on a line are input and processed. The result is one line of graphics.

Pin-block	Pin-block Code	Pins	Pin No.
1	2^7 = 128		1
			2
			3
2	2^6 = 64		4
			5
			6
3	2^5 = 32		7
			8
			9
4	2^4 = 16		10
			11
			12
5	2^3 = 8		13
			14
			15
6	2^2 = 4		16
			17
			18
7	2^1 = 2		19
			20
			21
8	2^0 = 1		22
			23
			24

As an example, suppose you want to fire pin-blocks 1, 2, 5 and 8 simultaneously. Then you complete the following sum:

Input code=Pin-block 1 code+Pin-block 2 code+Pin-block 5 code+Pin-block 8 code

$$ = 2 ^ {7} + 2 ^ {8} + 2 ^ {9} + 2 ^ {0} $$

$$ = 1 2 8 + 6 4 + 8 + 1 $$

$$ = 2 0 1 $$

Thus, the value 201 is entered in the CHR\$ function in order to print a single column of dots resulting from firing pin-blocks 1, 2, 5 and 8.

For our final example, refer to the standard density designation in Table 5.1. This setting is given by ESC+K+n₁+n₂. Suppose you wish to print 100 columns of dots, where every column fires pins 1 and 8 only.

You first compute the values of n_1 and n_2 which define the number of columns to be printed.

$$ \begin{array}{r l} {2 5 6) \frac {0 (n _ {2})}{1 0 0}} & {, \mathrm{so} n _ {2} = 0 \mathrm{and} n _ {1} = 1 0 0} \ {\frac {0}{1 0 0 (n _ {1})}} & {} \end{array} $$

Our control code ESC+K+n1+n2 now translates into:

LPRINT CHR\(27) + "K" + CHR\(100) + CHR\$(0);

Next compute the code for firing pins 1 and 8 simultaneously:

Input Code=Pin 1 Code+Pin 8 Code =2^7+2^0 =128+1 =129

Finally, we incorporate our two calculations into the following program. Note that lines 20 and 30 are necessary for the proper execution of this program on many IBM-compatible computers.

Such BASIC statements suppress CR and LF codes and enable printing on a full line without unwanted "breaks". Programs which include statements such as lines 20 and 30 cannot use LPRINT to print data. In such cases, PRINT# statements must be used. Line 90 is necessary to CLOSE all open files.

10 REM STANDARD DENSITY
20 WIDTH "LPT1:", 255
30 OPEN "LPT1:" AS #1
40 PRINT#1, CHR(27) + "K" + CHR(100) + CHR$(0);
50 FOR I = 1 TO 100
60 PRINT#1, CHR$(129);
70 NEXT I
80 PRINT#1, CHR$(10);
90 CLOSE
100 END 

24-Pin Bit Image Mode

In the 24-pin bit image mode, all 24 pins of the print head may be fired. In this mode, 3 data bytes must be sent to the printer for each column. The 24 pins in the print head are divided into three portions, the upper 8 pins, middle 8 pins and lower 8 pins.

As an example, suppose you want to fire pins 1, 2, 5, 8, 9, 11, 12, 21 and 24 simultaneously. Then you determine the following three values:

Byte 1: Input code=Pin 1 code+Pin 2 code+Pin 5 code+Pin 8 code

$$ = 2 ^ {7} + 2 ^ {6} + 2 ^ {3} + 2 ^ {0} $$

$$ = 1 2 8 + 6 4 + 8 + 1 = 2 0 1 $$

Byte 2: Input code=Pin 9 code+Pin 11 code+Pin 12 code

$$ = 2 ^ {7} + 2 ^ {5} + 2 ^ {4} $$

$$ = 1 2 8 + 3 2 + 1 6 = 1 7 6 $$

Byte 3: Input code=Pin 21 code+Pin 24 code

$$ = 2 ^ {3} + 2 ^ {0} $$

$$ = 8 + 1 = 9 $$

Thus, the three bytes for a single column of dots are entered as CHR\(201);CHR\(176);CHR\$(9);

Refer to the 24-pin standard density command in Table 5-1. This setting is given by ESC+*+m+n1+n2, where m=32. Suppose you wish to print 100 columns of dots, where every column fires pins 1, 2, 5, 8, 9, 11, 12, 21 and 24 as above.

As in the 8-pin example on page 5-7, n_1 = 100 and n_2 = 0 . Our control code ESC + * + m + n1 + n2 now translates into LPRINT CHR\(27) + “*” + CHR\(32) + CHR\(100) + CHR\(0);

If we incorporate this information into a program, we might have the following:

10 REM 24 PIN STANDARD DENSITY
20 WIDTH "LPT1:", 255
30 OPEN "LPT1:" AS #1
40 PRINT#1, CHR(27) + "*"+CHR(32) + CHR(100) + CHR(0);
50 FOR I = 1 TO 100
60 PRINT#1, CHR$(201);
70 PRINT#1, CHR$(176);
80 PRINT#1, CHR$(9);
90 NEXT I
100 PRINT#1, CHR$(10);
110 CLOSE
120 END 

Before proceeding with examples of each graphics control command, three important points are worth noting.

First, bit image graphics automatically sets the printer to single direction (left to right) printing. This is done to ensure that dots are correctly aligned vertically.

Second, the graphics mode is released immediately following the printing of all bit image data. Printing will return to the text mode.

Third, any bit image data are not affected by MSB control commands.

Code: 27,65,n DEC 1B,41,n HEX

Input Format: LPRINT CHR\(27) + "A" + CHR\(n);

Comments:

• ESC+2 must be input after ESC+A+n for 172 inch paper feed to become effective.
  ● ^1/72 inch paper feed is valid for 0≤n≤85.
• The paper feed amount is not exactly 172 inch, for the minimum unit is 1180 inch.

Comments:

- DIP switch 1-3 also controls the auto line feed function (refer to section 2.4). Setting this switch to the ON position is equivalent to executing the ESC+5+n command. Similarly, setting the switch to the OFF position is equivalent to executing the ESC+5+m command.

- LF is tied to CR in this mode.

LINE FEED (LF):

Causes data in buffer to be printed and then executes a single line feed.

Name: LF

Code: 10 DEC 0A HEX

Input Format: LPRINT CHR\$(10);

Comments:

- When the new line position falls within the perforation skip area, the paper advances to the next top of form position.

- If there is no data, "space" data (ASCII 32), or blanks between HT print positions in the buffer, LF feeds the paper by only 1 line.

- The amount of spacing generated by LF is a function of the paper feed amount setting.

- LF code releases single-line double width printing set by SO.

- DIP switch 2-6 controls the Automatic CR function. When this switch is OFF, LF executes a single line feed. The carriage, however, does not return to the left margin position. When this switch is ON, a Carriage Return command (CR) is added to each Line Feed (LF).

FORM FEED (FF):

Feeds paper to next top of form position after first printing any data in the buffer.

Name: FF

• Single-line, /216 inch paper feed is valid for 0 ≤ n ≤ 255 .
• This command sets the paper feed for ONE line only. Subsequent paper feed returns to previous setting. However, the carriage does not return to the left margin position. Instead, printing of next line begins where previous printing left off.
• This command does not release single-line double width printing.
• The paper feed amount is not exactly 12 inch, for the minimum unit is 1180 inch.

^n/216 INCH REVERSE DIRECTION SINGLE LINE PAPER FEED:

Prints out the data in the print buffer and feeds the paper 12 16 inch in reverse direction.

Comments:

• Reverse, single line 12 inch paper feed is valid for 0 ≤ n ≤ 255 .
• This command sets reverse direction paper feed for one line only. Subsequent paper feed returns to the previous setting. The carriage will not return, however, to the left margin position. Instead, the printing of the next line begins where the previous printing left off.
• This command does not release single-line double width printing.
• The paper feed amount is not exactly 12 16 inch, for the minimum unit is 1180 inch.

Notes:

Name: ESC+w+n n=0,1,2,3,4

Code: 27,119,n DEC 1B,77,n HEX

Input Format: LPRINT CHR\(27) + "w" + CHR\(n);

Comments:

- This command is operational only when the FONT and PITCH selector switches are set to "Pgm".

●Pitches are set as follows:

n=0: 10 characters per inch (25.4 mm)	HMI=12
n=1: 12 characters per inch (25.4 mm)	HMI=10
n=2: 15 characters per inch (25.4 mm)	HMI=8
n=3: 17 characters per inch (25.4 mm)	HMI=7
n=4: proportional spacing

- This command releases any previous character pitch settings.

- Execution of ESC+w+n alters character pitch only and does not affect the character font.

PROPORTIONAL SPACING (PS) MODE:

Sets printing using proportional spacing between characters.

Name: Setting: ESC+P Release: ESC+Q

Code: Setting: 27,80 DEC 1B,50 HEX Release: 27,81 DEC 1B,51 HEX

Input Format: Setting: LPRINT CHR\$(27) + "P"; Release: LPRINT CHR\$(27) + "Q";

Comments:

• This command is operational only when the FONT and PITCH selector switches are set to "Pgm".
• In proportional spacing mode, the SP spacing amount is determined by the current HMI. The BS spacing amount is equal to that of the character or SP immediately input prior to executing BS.
  ●Proportional spacing can also be set by the pitch selector switch.
• ESC+Q releases proportional spacing. The subsequent spacing amount is determined by the HMI.
  ●Proportional spacing is not released by ESC+X.
  ●Proportional spacing is released by ESC+S.

HORIZONTAL MOTION INDEX (HMI) SET:

Sets the amount of carriage spacing after printing or spacing, to (n-1)/120 inch (0.21 mm).

Name: ESC+US+n 1≤n≤126

Code: 27,31,n DEC 1B,1F,n HEX

Input Format: LPRINT CHR\(27) + CHR\(31) + CHR\$(n);

Comments:

HMI is the distance between characters to be printed or the distance that the carriage moves when SP code is executed. This distance is defined in multiples of 1/120 inch (0.21 mm).

For example, in 10 pitch which 10 characters per inch can be printed, the distance between characters is 1/10 inch. Therefore, HMI is 12 indicated by multiples of 1/120 inch. Minimum HMI is 0, maximum is 125 (1.04 inch nominal). HMI is set freely among these values by this command. When HMI=0, no carriage movement occurs.

• When the printer is powered up 10 pitch is automatically set.
  ●HMI affects SP, BS, HT and ESC+HT+n.
• ESC+S resets HMI to that specified by the pitch selector switch.
• Changing the HMI does not affect the left/right margin.
• If n ≥ 128 , the value is processed as n - 128 .
• When n = 0 or 127, next data is used for n .

HORIZONTAL MOTION INDEX (HMI) RESET:

Resets HMI to value defined by the pitch selector switch.

Name: ESC+S

Code: 27,83 DEC 1B,53 HEX

Input Format: LPRINT CHR\$(27) + "S";

Comments:

-ESC+S does not reset VMI.
- Resetting the HMI does not affect the left/right margin.

VERTICAL MOTION INDEX (VMI) SET:

Sets line spacing pitch to (n-1)/48 inch.

Name: ESC+RS+n 1≤n≤126

Code: 27,30,n DEC 1B,1E,n HEX

Input Format: LPRINT CHR\(27)+CHR\(30)+CHR\$(n);

Comments:

VMI is the distance between lines, or the distance that the paper (platen) moves for LF code. This distance is defined in multiples of 1/48 inch (0.53 mm).

For example, when 6 lines are printed in an inch, the distance between lines is 1/6 inch. Therefore VMI is 8 indicated by multiples of 1/48 inch. Minimum VMI is 0, maximum is 125 (2.60 inch nominal). VMI is set freely among these values by this command. When VMI=0, no paper movement occurs.

• When the printer is powered up, 18 inch line feed is set.
  ●VMI affects LF, VT, ESC+LF, ESC+U, ESC+D, ESC+FF+n and ESC+VT+n.
• Changing the VMI does not affect the top/bottom margin.
• If n ≥ 128 , the value is processed as n - 128 .
• When n = 0 or 127, next data is used for n .

BI-DIRECTIONAL PRINTING MODE:

Sets bi-directional printing.

Name: Setting: ESC+/Release: ESC+

Code: Setting: 27,47 DEC 1B,2F HEX Release: 27,92 DEC 1B,5C HEX

Input Format: Setting: LPRINT CHR\$(27) + "/"; Release: LPRINT CHR\$(27) + "\";

Comments:

• Bi-directional printing means that printing occurs during the left-to-right movement of carriage as well as on the right-to-left return trip.
• In single direction printing mode, the carriage is only moved left-to-right or only moved right-to-left.
• In bi-directional printing mode, the carriage is moved by the shortest way.

BACKWARD PRINTING MODE:

Prints data from right to left.

Name: Setting: ESC+6 Release: ESC+5

Code: Setting: 27,54 DEC 1B,36 HEX Release: 27,53 DEC 1B,35 HEX

Input Format: Setting: LPRINT CHR\$(27) + "6"; Release: LPRINT CHR\$(27) + "5";

Comments:

●Backward printing is released by CR code.
- In backward printing, the SP code moves the carriage right-to-left while the BS code moves the carriage left-to-right.
-Tabulation, bit image data, CR, and paper feed functions are unaffected by backward printing.
- Any data to be printed to the left of the left margin is overprinted at the left margin.

AUTOMATIC LINE FEED MODE:

Automatically executes a Line Feed following a Carriage Return.

Name: Setting: ESC+" Release: ESC+#

Code: Setting: 27,34 DEC 1B,22 HEX Release: 27,35 DEC 1B,23 HEX

9. Interfaces

9.1 Parallel Interfacing

Communication with a computer is accomplished through a parallel interface based on the Centronics standard.

Specifications:

●data transfer speed: 1000 cps minimum
•synchronization: external STROBE pulse
- logic levels: TTL
- handshaking: BUSY and ACK signals
- connector type: 57-30360 (AMPHENOL) or equivalent

When the printer is processing data, the BUSY signal is high. The printer will not accept new data from the computer. After the processing is completed, the BUSY signal goes low. (The BUSY signal is also high when the printer is OFF LINE). When this occurs, the ACK signal goes low indicating to the computer that the data has been processed and the printer is ready to accept more data. This handshaking routine occurs each time a character is sent to the printer.

	BUSY	SLCT	PO	ERROR
ON LINE	LOW	HIGH	LOW	HIGH
OFF LINE	HIGH	LOW	LOW	LOW
PAPER OUT	HIGH	LOW	HIGH	LOW

Table 9.2 Pin Configuration(Parallel)

Notes:

1. "INPUT" refers to a signal coming into the printer. "OUTPUT" denotes a signal exiting the printer.
2. "RETURN" denotes the return side wire of a twisted pair cable and is connected to signal ground.
3. All interface signals are at TTL levels.

Connector pin signals

STB... STROBE

• This is a synchronizing input signal to read data into the printer.
• This signal is normally high. Data is read in when it goes low.
• The pulse must be low for at least 1 micro-second.

DATA 1-DATA 8

• These are the input signals which carry the 8 data bits of information.
• The signal is read in synchronization with the STROBE pulse. A high level indicates a logical "1".
• The signal must be present 0.5 microsecond before and after the STROBE pulse.

ACK... ACKNOWLEDGE

• This is an output signal to the computer indicating that the printer is ready to receive the next block of data. It is sent out when the BUSY signal drops from high to low. Therefore, it can be thought of as a data request pulse.
• The signal is normally high. When the condition becomes true, the signal goes low.
• The ACK signal is automatically sent whenever the printer is switched ON LINE.

BUSY

• This output signal indicates the status of the printer. The signal is high when the printer is busy and cannot receive data.
  ●The signal is high under the following conditions:
• receive buffer full
• printer is processing data
• printer is OFF LINE
• printer is in an error condition

PO... PAPER OUT

• This output signal indicates that paper out detector detects the absence of paper.
• The signal is normally low and goes high during a "Paper Out" condition.

SLCT... SELECT

- SELECT is an output signal which indicates the ON LINE or OFF LINE state of the printer. The signal is high in the ON LINE state and low when OFF LINE.

●The printer enters the ON LINE state:
1. when the printer is turned on
2. when PRIME is received
3. when the RESET command is received
4. when the ON LINE switch is pressed

●The printer enters the OFF LINE state:
1. when the printer is out of paper
2. when the printer is switched OFF LINE

AUTO FEED XT (AFXT)

• This input signal determines if a line feed (LF) command will be added to each carriage return (CR).
• When AFXT is low, CR+LF action occurs. When AFXT is high, only a carriage return is performed.
• DIP SW1-3 can alter the response by the printer to an signal. If SW1-3 is ON, the printer will perform a CR+LF regardless of the level of the incoming signal. When SW1-3 is OFF, this automatic action is disabled.

SG... SIGNAL GROUND

- The twisted pair return wires (pins 19–30) are connected to signal ground.

FG... FRAME GROUND

- Frame ground is the same as chassis ground.

+5 V

This is for evaluation only. It should not be used to supply power for external equipment.

PRIME

This input signal is used to initialize the printer. The signal is normally high and goes low to reset the printer. It can be received anytime during printer operation.

ERROR

This output signal is an "error" or "fault" condition. Normally high, this signal goes low when an error occurs. An error condition can be caused by:

1. a "Paper Out" condition.
2. the printer is OFF LINE
3. an overload condition exists

Signal Descriptions

FG...Frame Ground

●Frame ground is the same as chassis ground.

TXD...Transmit Data

- Outputs serial data to the computer. SPACE indicates "0" data; MARK indicates "1" data.

RXD...Receive Data

- Inputs serial data from the computer. SPACE indicates "0" data; MARK indicates "1" data.

SG...Signal Ground

- Connected to signal ground of printers circuit board.

DTR...Data Terminal Ready

●This signal indicates that the printer is busy.
- When this signal is in the SPACE condition (+ side, EIA level), the printer is ready for data reception when DIP SW 3-6 is set to OFF.

Designation of Signal Polarity for Reverse Channel (or DTR)

This signal is sent to inform the computer that data reception is not possible at the present time, even though the printer might be on-line. Printer and computer polarities can be matched by setting DIP switch 3-6. Refer to page 2-6.

ON: This signal in "SPACE" informs the computer that the printer cannot receive transmitted data.

OFF: This signal in "MARK" informs the computer that the printer cannot receive transmitted data.

DIP switch 3-6 is set OFF prior to shipping from the factory.

MARK logic "1" (-27 V to -3 V)

SPACE logic "0" (3 V to 27 V)

Protocol

This printer supports two types of protocol: XON/XOFF and DTR. DTR protocol uses a DTR signal to indicate the condition of the printer, while XON/XOFF protocol uses an ASCII code corresponding to XON/XOFF.

DTR Protocol

When the input buffer is reduced to less than 128 bytes, the printer indicates that data reception is no longer possible by setting the DTR to the "MARK" condition. In this condition, the computer is forced to stop transmitting data. Should the computer continue transmitting, all excessive data will be ignored by the printer. The DTR is also set to "MARK" when the printer is off-line. When the input buffer is restored to a level of 288 bytes (when DIP switch 3-7 is OFF) or more, the DTR changes to the "SPACE" condition.

XON/XOFF Protocol

When the input buffer is reduced to less than 128 bytes, the printer outputs the XOFF character. When this character is output, the computer is forced to stop transmitting data. Should the computer continue transmitting, all excessive data will be ignored by the printer. The XOFF character is also output when the printer is off-line. The XON character is output when the input buffer is restored to a level of 288 bytes (when DIP switch 3-7 is OFF) or more, when the power is turned on, or when the printer goes from the off-line to the on-line condition.

$$ \mathrm{XON} = 1 1 _ {\text { H E X }} (1 7 _ {\text { D E C }}) $$

$$ \mathrm{XOFF} = 1 3 _ {\text { H E X }} (1 9 _ {\text { D E C }}) $$

10. Maintenance

The printer does not require any routine maintenance. However, reasonable care of the printer will extend its life. The following preventive and periodic measures are recommended:

Preventive Maintenance

• Keep all liquids away from the printer. Accidental spillage of a liquid into the printer can cause severe damage.
• Do not block the air flow around the printer. Do not place books, paper, or other items on top of the printer.
• Special care should be taken to protect the printer if it is used in an unfriendly environment such as a machine shop, a dusty or sandy area, etc.
• When transporting the printer, be sure the carriage stopper is in place. This will help prevent damage to the print head.
  ●The life of the print head can be extended by observing a few simple precautions.
• Do not operate the printer without paper and a ribbon cassette installed.
• Avoid continuous use of the same pins (underline, semi-graphics, etc.) without allowing the print head time to cool.
• Do not obstruct the movement of the print head while in operation.
• If the printer is not going to be used for an extended period, unplug the power cord.

Periodic Maintenance

Cleaning the unit is the most important action the user can perform. The frequency of cleaning is dependent upon the environment.

• Turn the power OFF.
• Clean the case and covers with a soft cloth. Use any mild commercial cleaner.
• Remove the top and the smoked plastic covers. Vacuum or dust the inside area of the unit. Be very careful not to damage the flex ribbon cable and the carriage drive belt.
• The platen should be cleaned with denatured alcohol only.
• The carriage guide bar can be lubricated with a very light oil.

Ribbon Cassette

A single ribbon permits the printing of about 3 million characters. When the printing starts to fade, gently push the counter spring in the ribbon cassette hole with the tip of a ballpoint pen or other object. Once the ribbon cassette is mounted onto the carriage and printing is performed for a short time, the characters become thicker.

Note:

Do not re-ink the ribbon before printing starts to fade. If the ribbon has too much ink the characters may smear when printed.

- Wear and tear of the print head pins may cause serious damage of the ribbon and printing to fade. In such case the printer needs servicing.

Troubleshooting

Most problems associated with the printer can be traced to improper setup, installation, or cabling. Table 10.1 will assist the user in identifying and

correcting some of the more common problems. If you need additional help, contact the store from which the unit was purchased.

Paper

1. Continuous paper

A list of the paper which may be used with this unit is provided below.

Width: 4\~15.5 inches (102\~394 mm) continuous paper with perforations on either side.

Quality and number of sheets: up to 4 sheets can be used; the relationship between the paper quality and number of sheets is given below.

Types of paper	Sheets	Thickness
		(paper weight in pound)	(paper weight in g/m2)
Fine-quality paper	1	16~20	61~75
Non-carbon paper	2	11~14 (17)(17) is only for the last sheet.	41~53 (64)(64) is only for the last sheet.
	3
	4
Multi-layer paper with carbon	2

• The multi-layer paper with carbon is such that the inserted carbon sheet is equivalent to a sheet of paper and so the maximum number of sheets of such paper is 2.

Note:

- The “paper weight in pound” represents the weight of the paper indicating the weight of 500 sheets [17×22 inches (432×559 mm)] in pound.

2. Single Sheet

Width: 4\~16.5 inches (102\~419 mm)

Height: 5\~14.3 inches (127\~363 mm)

Thickness (paper weight in pounds): 14\~24 pounds (Only 1 sheet). (paper weight in g/m²): 53\~90 g/m² (Only 1 sheet)

- The printer will handle papers up to 0.013 inch (0.32 mm) thickness, providing they roll smoothly and easily around the platen. Multiple copies will be readable up to 4 copies of 14 lb. weight paper with chemical release paper.

●Paper should be within operating temperature and humidity range at least 24 hours prior to use.
