OVERVIEW This specification defines the following that are realized by the firmware, for the OKIPOS 425S/D (POS Printer) OKI Standard Version.

• OKIPOS 425S : OKI Single Standard Version
• OKIPOS 425D : OKI Dual Standard Version <Conventions in this specification document> This printer comes in two models, 1-Roll Model and 2-Roll Model. The 2-Roll Model printer has three roll paper modes, Receipt, Journal, and Receipt+Journal. The 1-Roll Mode printer has only the Roll paper mode. In this specification document, if the 1-Roll Model is not specifically mentioned when the 1-Roll Model is involved, for “Receipt (mode)”, read “Roll Paper (mode)”, and ignore the descriptions for “Journal (mode)” or “Receipt+Journal (mode)”. <Definitions of Off-line> This printer is not equipped with the On-line/Off-line switch. It becomes Off-line under the following conditions: (1) (2) (3) (4) (5) (6) (7) During the period from POW ON or initialization of the mechanism prompted by the reset from the interface, to the time communications become available. During execution of local test. When the cover is opened (“Cover Open Alarm” on the menu is set to “Yes”) During paper feed by the switch. Printing has stopped due to Paper End. (Paper End of Receipt, Journal, or Receipt+Journal selected by ESC c4.) Recoverable Error has occurred. (Except Head Thermal Alarm, SP Thermal Alarm or LF Thermal Alarm) Unrecoverable Error has occurred. At Off-line, an On-line/Off-line status that is sent by GS a n, ESC DLE a Pno n, GS ENQ, DLE EOT n, and ESC DLE r Pno n becomes off-line, and the I/F becomes Busy. In the case of (3) through (6), the I/F becomes Busy only if “Off-line Busy Control” on the menu is set to “Yes”
• Each I/F becomes Busy in the following manner.
• With the Parallel model (Centronics I/F), the Busy signal becomes High at Off-line.
• With the Serial model (RS232C I/F), the following Busy control is performed at Off-line. If handshake is DTR/DSR, the DTR signal will change to MARK. If handshake is XON/XOFF, DC3 will be sent. 41049421PS Rev.3

Note 2 In No.4, if the lever is on the tractor side, the Sprocket Print Test becomes effective. If the lever is not on the tractor side, the Slip Print Test becomes effective. Note 3 In Nos. 5, 8 and 10, if the lever is on the tractor side, these local functions become invalid, and the printer starts in normal mode. Nos.1 ~ 3, 6, 7 and 9 become effective regardless of the lever state. Note 4 In Nos.1~ 3, the print widths will be those set in the menu “Width of Roll Paper”. Note 5 In Nos.1 ~ 4 and 10, if SW1 is pressed, printing suspends. When the SW1 is pressed again, the printing resumes. Note 6 In No.1 ~ 5, 8 and 10, if the cover is opened, printing suspends. When the cover is closed, printing resumes. (This is limited to only with the setting of Menu "Cover Open Alarm = YES", suspend in the cases of No.6 and 7.) Note 7 In each local function, if the tractor lever is switched, Media Does Not Match Alarm (1) will result. When the tractor is returned to the original position, the alarm is cleared and test printing resumes. 41049421PS Rev.3 12 /

This function creates test data internally as if the printer received the data from the host, and prints the test pattern.

Printer Status in Local Test Mode When the local test begins, the printer cannot receive data (*1). Even when a recoverable alarm occurs, the test mode is not cleared, and the test print resumes when the alarm element is cleared. The condition to end the local test is to turn the power off, but the local test is terminated when I- PRIME signal (Parallel model) /Reset signal (Serial model) is received or a fatal alarm occurs. (*1) When the printer cannot receive data, each I/F presents Busy as follows.

• Parallel model (Centronics interface): Busy signal → High
• Serial model (RS232C I/F): Busy control as follows. When handshake is DTR/DSR: DTR signal → MARK status When handshake is XON/XOFF: Sends DC3

2.4 MENU FUNCTION (Receipt)

Overview The menu function is the local function that sets each mode to control the printer and adjusts it. This mode has the following items, saved in the E2P-ROM. This information is printed only when the menu mode is activated at Power On, and the information can be written over from the operator panel. Menu Print is printed in Receipt Mode. For the printer’s initialization state, each mode is set according to the information of this area.

Yes *Default of 1-Roll Model is No. Yes

16K 76.2mm 69.5mm Note 1) In the 1-Roll Model, an auto cutter unit cannot be installed. Note 2) I/F control information (baud rate and etc.) and customer display connection/disconnection of serial model are set by DIP-SW of the I/F board. Note 3) MICR Unit selection has the following two types for MICR Read test (Refer to Section

2.3.2.6.): “Yes (CMC-7),” and “Yes (E-13B)” Normally, either selection is recognized as

an actual installation status of MICR Unit, and MICR type is selected by designation of the command. 41049421PS Rev.3 20 /

Start To start the Menu Mode, turn the printer on while holding down SW2 + SW1. When the printer’s initialization ends correctly, the printer prints the title “Menu Print” and all the menu items and set values. Then, the printer line-feeds until the print result goes beyond the Manual Cutter position, prints the item/set value immediately after “Menu Print”, then, waits for a switch to be pressed.

Operation The switch functions during the menu mode are as follows: 41049421PS Rev.3 Switch Function SW2 Advances the set values of the Menu Item, one at a time. From the last set value, returns to the first set value. SW3 Ends Menu Mode. Registers the set values in EEPROM, then, prints the end message “Menu End” and returns to the same initialized state as at power on. SW1 Advances the Menu Items, one at a time. From the last Menu Item, returns to the first Menu Item. SW4 Feeds the receipt, by one line. 21 /

2.5 HEX DUMP FUNCTION (Receipt)

This function converts received data, as it is, to character codes, and prints it in the Receipt mode. The printed contents are as follows: Upon receiving one byte, the printer divides it into three characters, High-nibble, Low-nibble and a space. Regarding these as 1 block, the printer prints 8 blocks in one line, then, prints the same data in the character format. Upon entering the HEX dump mode, the printer prints “Hex Data Dump”. (Title printing)

Hex data ASCII data How to Print (1) (2) (3) (4) If it does not receive data after 150ms have passed since receiving last data, the printer starts printing (CR) if it has some data. (If there is not enough data to form 8 blocks, spaces will be used.) If it subsequently receives data, the printer prints from a position next to the position at which the printing started. If it receives the I-PRIME signal (Parallel model)/Reset signal (Serial model), the printer starts printing if it has some data, then, feeds one line. Then, the printer is initialized. (If it does not have any data, the printer feeds one line and then, is initialized.) After the initialization, the printer starts up in dump mode again and prints. The line number is reset, however, and counting begins from “0000”.

• When I-PRIME signal (Parallel model)/Reset signal (Serial model) is hard reset (setting by Short Plug with Parallel I/F board and by DIP SW with Serial I/F board), it immediately starts initialization and does not continue hex dump. One line-feed is added for every 16 lines. The count begins from “0000” when the line number exceeds “FFF8”. 41049421PS Rev.3 22 /

2.6 PLATEN MAINTENANCE MODE

This function is for switching the platen position when the print head gap is adjusted in the production line. (1) How to start the mode Turn the power on while holding down SW2 + SW3 + SW1. *1 This mode can be executed even when the print head is not installed. *2 When this mode is being started, the initial platen position should be on the Receipt side. If the paper is already loaded in the Tractor mode, the platen should be on the Slip side. (2) How to operate Switch Function SW2 Moves the platen to the Receipt side. SW3 Moves the platen to the Slip side. SW1 Invalid SW4 (3) How to exit the maintenance mode Turn the power off. 41049421PS Rev.3 23 /

If n=0, the entire command is ignored. Perforation Skip set by this command is cleared when the page length is set for sprocket paper. Once set, the Perforation Skip area is not affected even if the line feed pitch is changed. To perform Perforation Skip, when a line feed by LF/CR (with Auto Line Feed enabled), ESC J n, ESC d n, or ESC % 5 n brings the position into the perforation skip area, then to feed paper to the next TOF position. If the setting is set as “Page Length ≤ Perforation Skip Area, that perforation skip setting becomes invalid, and previous perforation skip setting remains effective. Difference between ESC O and ESC N 00H: The command ESC O clears Perforation Skip while ESC N 00H is ignored. (In other words, the previous setting remains effective.) When the print sheet is Sprocket paper (with the option tractor installed), if setting a perforation skip area brings the present vertical position into the perforation skip area, the printer can still print one line even if the position is in the perforation skip area. Execution of the next forward line feed command feed paper to the next page’s TOF position. When the print sheet is Sprocket paper (with the option tractor installed) and the line feed pitch larger than the perforation skip area is set, if the line feed command that would prompt a jump over the perforation skip area is received, paper is fed as much as the designated amount of line feed. When the line feed pitch is set to 0, if n > 0. the perforation skip set command sets the amount of skip to “0”. (This clears Perforation Skip.) When the print sheet is Sprocket paper (with the option tractor installed) and the perforation skip area is set by this command, the setting becomes immediately effective within the current page. The default perforation skip area is now cleared. 41049421PS Rev.3 39 /

(b) This command is executed as data is received. (c) Be aware that in addition to this command, reception of a data sequence of 10H 04H n (01H ≤ n ≤ 05H) prompts the same operation as this command does. (Example) ESC * m n1 n2 (d) This command may not be used in the middle of a code sequence of other commands of more than two bytes. (Example) It must be made aware that when the host has sent ESC 3 in sending ESC 3 n, if DLE EOT 4 is sent, ESC 3 n will be processed as ESC 3 n=10H. (e) This command is disabled in the Printer Deselected state set by the Peripheral Device Select (ESC =). (f) If the ASB function is enabled by GS a or ESC DLE a, a status sent by this command and one by ASB must be distinguished, (g) If the value of n is outside the above range, this command is ignored. (Notes specific to Parallel Models) (a) Sends a status at a request from the host PC for Reverse Transfer. (b) If the Busy signal is at High, reception of this command is disabled. The Busy signal becomes High either when the receive buffer is full or in the Off-line state. (See Section 1 “Definitions of Off-line”.) (Hence, when an unrecoverable error has occurred, this command cannot be received.) (c) If the printer holds a status sent by ASB and one by this command, it sends the one by ASB first. (d) If there is not a request from the host PC for Reverse Transfer following the reception of this command, the printer holds data up to 100bytes (except the status data by ASB). Once the data it holds goes over 100bytes, reception of this command does not prompt the printer to generate data to send to the host. (Notes specific to Serial Models) (a) Sends only one byte without checking the status of the DSR signal in sending a status. (b) Processes while Off-line or in the Receive Buffer Full state.

The operations based on n are explained in the table below. 02H 03H Function If this command is received in the recoverable error state (*1), clearing of the receive buffer and print buffer, and clearing the cause of error prompt setting the print sheet to Receipt+Journal. (*2) (This command is ignored with any other error than recoverable error.) If this command is received in the state (*3) waiting for Slip, Validation or Check (MICR Mode), or when there is no Sprocket paper, the receive buffer and print buffer are cleared; then the print sheet is set to Receipt+Journal. (*2) (This command is ignored in any other states than Waiting.)

• Slip Paper Feed/Eject Alarm
• Auto Loading/Auto Parking Alarm
• Media Mismatch Alarm (1)/(2) *2 Nothing other than Receive Buffer, Print Buffer, and Print Sheet Mode will be initialized. When the Option tractor is installed and the lever is set to Tractor, if Paper Mode is Sprocket, the Sprocket Mode remains effective if the status is Paper present. *3 This is the state effective before an operation starts at insertion of paper. (2) Range of n: 02H ≤ n ≤ 03H (Notes) (a) This command is processed at reception. (b) (Parallel Models) Reception is disabled in the Off-line (Menu, “Off-line Busy Control” is “Yes”), Receive Buffer Full and an unrecoverable error state; hence, this command cannot be processed. (Serial Models) The command is processed even in the Off-line and Receive Buffer Full state. It is not processed in an unrecoverable error. (c) It must be noted that reception of a string of data as 10H 05H n (02H ≤ n ≤ 03H), in addition to this command, also prompts an operation by this command. Example) ESC * m n1 n2 (d) This command may not be used in the middle of a code sequence of other commands made of more than two bytes. (Example) It must be made aware that when the host has sent ESC 3 in sending ESC 3 n, if DLE ENQ 02H is sent, ESC 3 n will be processed as ESC 3 n=10H. (e) If DLE ENQ 02H is received in the recoverable error state, clearing the cause of error prompts clearing of the receive buffer and print buffer, then setting the print sheet to Receipt+Journal. For various settings by ESC !, ESC 3, and so forth, the printer retains the status effective at the time of error occurrence. This command and ESC @ can completely initialize the printer. Furthermore, this command is valid only if the errors are recoverable except for Thermal Error. 41049421PS Rev.3 93 / (f) DLE ENQ 03H is valid only during Slip Insert Wait or Validation Insert Wait. Hence, it must be confirmed prior to execution of DLE ENQ 03H that Slip or Validation has been selected by DLE EOT 05H or 06H, and insertion of either print sheet is being awaited. The print sheet will be Receipt+Journal once Slip Insert Wait or Validation Insert Wait is reset. (g) In the Printer Deselected states set by Peripheral Device Select (ESC=), the error recovery function (DLE ENQ 02H) is enabled while the insert wait cancel (DLE ENGQ 03H) function becomes disabled. (h) When the print sheet selected is Slip, if error recovery has been made after reception of DLE ENQ 02H, the print sheet will be Receipt+Journal. Hence, the Slip mode needs to be selected again by ESC c 0 04H in order to print Slip paper again. (i) If the value of n is outside the specified range, this command is ignored. (j) Reception of this command will not clear a status that has not yet been sent. [In the Serial mode, if the DTR signal is MARK, sending of a status prompted by Non-Realtime command (such as ESC u n) is awaited until the DTR signal changes to SPACE and no other commands or data are processed during this wait. In other words, there cannot be any occurrence of state (such as Recoverable Error and Paper Insert Wait) that would allow this command to become effective while there is still an unsent status.] (Notes) In case of MICR Mode: (a) When MICR Mode is selected by FS a 0, if error recovery has been made after reception of DLE ENQ 02H, the printer clears the contents of the receive buffer and print buffer, prompting Receipt+Journal. Hence, the MICR mode needs to be selected again by FS a 0 in order to print Check paper. (b) DLE ENQ 03H can reset the Check Insert Wait status in Check Paper Insert Wait state. Prior to resetting, it is necessary to check that the MICR mode is selected by DLE EOT BS 01H, and also the Check Insert Wait state. Once Insert Wait is cleared, the print sheet is set to Receipt+Journal. (c) Canceling Insert Wait by DLE ENQ 03H prompts clearing the receive buffer and print buffer. (d) This command is invalid during reading of MICR data. 41049421PS Rev.3 94 /

3.2.8.18 Real-time MICR Status Send

DLE EOT BS n Name: Real-time MICR Status Send HEX: 10H 04H 08H n DEC: 17 04 08 n Code Functions (1) (2) Creates(sends) real-time a 1-byte status of MICR if n=01H. This command functions only if the menu item “MICR Unit” is set to “Yes.” If the setting of Menu “MICR Unit” is “No,” the command is ignored to DLE EOT BS. If the MICR option is not installed and the setting of MICR Unit is “Yes,” the status is MICR Mode Deselected, prompting sending of this status. (3) This command is ignored during reading of Check paper. (4) It must be noted that reception of a data queue as 1DH 61H n (00H ≤ n ≤ FFH), in addition to this command, also prompts an operation by this command. Example) ESC * m n1 n2 (5) This command may not be used in the middle of a code sequence of other commands made of more than two bytes. Example) In sensing ESC 3 n from the host PC, if you send DLE EOT BS 01H past ESC 3, these commands are processed as ESC 3 n = 1DH instead. This must be kept in mind. (Notes specific to Parallel Models) (6) Sends a status when the host PC requests for Reverse Data Transfer. (7) If the Busy signal is at High, reception of this command is disabled. The Busy signal becomes “High” at Receive Buffer Full or at Off-line. (See Section 1 “Definitions of Off-line.”) (8) If the printer holds a status sent by ASB and another by this command, it sends the one by ASB first. (9) If there is not a request from the host PC for Reverse Transfer following the reception of this command, the printer holds data up to 100bytes (except the status data by ASB). Once the data it holds goes over 100bytes, reception of this command does not prompt the printer to generate data to send to the host. (Notes specific to Serial Models) (10) Sends one byte without checking the status of the DSR signal in sending a status. (11) Processes while at Off-line or in the Receive Buffer Full state. This process is not performed when an unrecoverable error has occurred. (12) MICR status is sent as follows:

When the MICR option is not installed and Menu Item “MICR Unit” is set to “Yes,” reception of this command will result in MICR Unit error (unrecoverable error). This command is valid only if designated at the start of the line. Designated in the middle of the line, the command is ignored in its entirely. Upon reception of this command, the printer enters the MICR mode and waits for insertion of Check paper. The printer waits for insertion of Check paper until DLE ENQ 03H is received, the Insert Wait time (t1) set by ESC f has lapsed, the printer is reset, or the power supply is shut off. Whether the status is MICR Mode Selected or Deselected can be checked by DLE EOT BS. The printer only processes the real-time commands (DLE EOT n, DLE EOT BS n, DLE ENQ n, ESC DLE r Pno n, or GS ENQ) while waiting for the Check paper to be inserted or reading the Check paper. The Check paper insert wait status can be cancelled by DLE ENQ 03H. In this case, the data in the print and receive buffers are cleared. The Check paper insert wait status can be checked by DLE EOT BS. Reading the Check paper, the printer creates (sends) a result to the host PC.

If reading did not end normally neither Bit 0 nor Bit 1 carries any meaning. In the following cases, the status is read anomalous end (Bit 5=1).

• Check Insert Wait has been cleared by DLE ENQ 03H.
• The Insert Wait Time (t1) set by ESC f has elapsed.
• Characters to be read could not be found.
• Less than five characters are recognizable.
• More than three characters are unrecognizable.
• The character font is not what is designated.
• The printer is waiting for Check paper to be inserted and the lever is switched to Tractor. In the case of Check Read anomalous end (Read status bit5=0), the printer sends “Header~NUL” to the host PC but does not eject the Check paper. If any command other than FS a 0, FS a 1, FS a 2, FS b, and real-time commands (DLE EOT n, DLE EOT BS n, DLE ENQ n, ESC DLE r Pno n) has been processed, the printer ejects Check paper and goes into Receipt+Journal Mode. (The real-time commands “GS ENQ” prompt ejection of Check paper as “GS” is processed in the receive buffer.) In the case of Check Read anomalous end (Read status bit5=1), the printer ejects Check paper to set MICR Mode to Deselected. It moves to Receipt+Journal Mode. If Check Read action results in JAM, paper feed alarm occurs. When the alarm condition is cleared, the status is Check Insert Wait. When paper feed alarm has occurred, if DLE ENQ 02H is received, the alarm status is cleared and MICR Mode is deselected; then the printer goes into Receipt+Journal mode. The printer ignores the Real-time command while sending “Header~NUL.” Even if the ASB function is selected, the printer does not send ASB status while reading, and sending “Header~NUL.” In the case of Parallel Mode, the printer sends “Header~NUL” at the request from the Host PC for Reverse Data Transfer, then sends ASB status at a next Reverse Data Transfer request. Read status will be hold until reception of either ESC @, FS a 0 n, Menu setting command, IPRIME signal (Parallel model), or Reset signal (Serial Model). (DLE ENQ n does not initialize Read status.) All switches are invalid between the start of MICR read and ejection of Check paper. In the case of Check Read Normal End (Read status bit5=0), reception of this command prompts the printer to eject Check paper and go into the Check Insert Wait state again. With the option tractor installed and the lever set to the tractor, reception of this command will be ignored. If MICR Reader Unit communication error has occurred, MICR Unit error (unrecoverable error) occurs. 41049421PS Rev.3 99 / (Notes specific to Serial models) (a) With DTR/DSR Control selected, the printer sends a result of reading Check paper after confirming that the host PC is enable to receive (DSR Signal is in SPACE). If the host PC is not enable to receive (DSR Signal is in MARK), the printer waits until it becomes enabled to receive. With XON/XOFF selected, the printer sends a result of reading Check paper irrespective of the status of the DSR signal. (b) While the printer sends status data read, if the host PC becomes unable to receive (DSR signal is in MARK), it keeps sending status data.

(Vertical direction: 144DPI) Uni-direction printing takes place regardless of the Uni-direction Print command (ESC U) settings. Pno specifies the number of bytes following ESC DLE B Pno. (MSB: Invalid) Pm selects the CODE128 Modes A, B or C. Valid only when the CODE128 is selected, and when anything other than CODE128 is selected, the command sequence becomes ESC DLE B Pno DATA. 41H: CODE128(Set A) Start Code is START CODE A. (Starts in the CODE A Mode.) 42H: CODE128(Set B) Start Code is START CODE B. (Starts in the CODE B Mode.) 43H: CODE128(Set C) Start Code is START CODE C. (Starts in the CODE C Mode.) For any other value, the entire command is ignored. DATA indicates bar code data and MSB is invalid. Since Start/Stop Characters of CODABAR vary, however, they are included in the DATA. For the number of characters (number of data) that become effective by this command, refer to (11). For the range that can be actually printed, refer to the Bar Code Style Select and Size Set command (ESC DLE A). 41049421PS Rev.3 116 / (5) Block change conditions that trigger printing: (a) Condition proceeding valid print bar code that triggers printing DATA-1 Barcode-1 If a block of bar code data (barcode-1) follows a block of characters (including spaces) or bit image graphics (above DATA-1), the block change triggers the “data-1” to print. The only case this is not applicable is when the DATA-1 is SKIP. SKIP, too, however, triggers printing if the 144DPI calculation results in a fraction. (b) Block change condition that triggers valid print bar code to print Barcode-2 DATA-2 If a block of bar code data (barcode-2) proceeds a block of data (above DATA-2) that is a print start command, or characters (including spaces) or bit image graphics, the block change triggers the “barcode-2” data to print. (c) Block change condition that triggers printing when valid print bar codes continue Barcode-3 Barcode-4 If a different bar code mode is set after (or before) the above barcode-3 and then this command is received, the block change triggers the barcode-3 data to print. A different bar code mode here means a change(s) in the following settings:

• Whether human readable characters Present/Not-present (6) The vertical current position after bar code printing shall be the print end position. When the block change triggers printing according to the conditions described in (5), the baseline that becomes the reference for the current vertical position shifts by the line feed that accompanies the bar code printing. As a result, the print position will become as follows: DATA-1 Barcode-1 Barcode-2 DATA-2 (7) When bar code data exceeding the right margin is received, the entire command is ignored, and next print start position (horizontal current position) shall become the right margin position. When the Identical Data Print is cleared in Receipt+Journal mode, if the print start position exceeds Receipt’s right margin on the Receipt side or Journal’s right margin on Journal side, the entire command is ignored, and next print start position will become Journal’s right margin position, whether the print start position is on Receipt side or Journal side. (Since Block Change Check is performed before Right Margin Check, however, even when the right margin is exceeded, if the block change conditions that trigger printing are met, the block change triggers applicable data to print.) For how to calculate the bar code width, refer to the Bar Code Style Select and Size Set command (ESC DLE A). 41049421PS Rev.3 117 / Print example when bar code exceeding right margin is received after Identical Data Print is cleared in the Receipt+Journal mode: Data received

Journal Receipt Journal Bar code settings of Barcode-1 and Barcode-2 are identical. With the reception of Barcode-1, the block change triggers the character “A” to print. With the reception of the character “B” before LF, printing, then, carriage return and line feed take place. Note 1) The print result in the above figure is for the bar code height of 7/72 inch and no human readable character present. (8) When this command is received in the Validation mode, the entire command is ignored. (9) The bar code print line is Left Align, regardless of the setting of the Position Align command (ESC a). The same applies to the line that is printed triggered by the block change with the reception of this command. (10) In Slip mode and Sprocket mode, if the bar code exceeds the printable area in the vertical direction while it is being printed over multiple lines, it is printed overlapping. 41049421PS Rev.3 118 / (11) The number of characters that become valid in this command is as follows (Check Digit code is counted as 1 character): (a) EAN8 8 characters (fixed) (b) EAN13 13 characters (fixed) (c) UPC-A 12 characters (fixed) (d) UPC-E 6 characters (fixed) (e) CODE39 50 characters (maximum number of characters) (f) Interleaved 2 of 5 50 characters (maximum number of characters) (g) CODE128(Set A,B,C) 50 characters (maximum number of characters) (h) CODABAR 50 characters (maximum number of characters)

• For (a) through (d), the number of characters is fixed to the above. When the Pno value is not the fixed number of characters, the entire command is ignored.
• For (e) through (h), they are valid as long as they do not exceed the maximum number of characters. If the Pno value ((g): Pno - 1 value) exceeds the maximum number of characters, the entire command is ignored.
• In the Interleaved 2 of 5, if the number of characters is an odd number, add the character “0” in front of the data. (Ex. 123 → 0123)
• In the CODE128’s CODE C, if the number of characters excluding the Check Digit Character and 3AH~3CH is an odd number, add the character “0” in front of the data. (Ex. 123 → 0123)
• For CODABAR, Start/Stop Characters are included in the number of characters. (12) By sending the Check Digit Character at the end of DATA, the Check Digit can be automatically generated. This is not applicable to UPC-E or CODABAR, however. If the Check Digit Character is not at the end of DATA, it is handled as an invalid code, and for EAN8, EAN13 and UPC-A, the entire command is ignored.

Default Initialization to defaults takes place under the following conditions: at POW-ON, or reception of IPRIME signal (Parallel model)/Reset signal (Serial Model), software reset commands, or Menu Item set command, or end of Menu operation. (With this printer, end of local test will not prompt default initialization on any setting.) The following pages describe the statuses in detail. <<Cautionary notes at reception of I-PRIME signal (Parallel model)/Reset signal(Serial model)>> (1) If data still remains in the receive buffer or the print buffer at reception of I-PRIME signal (Parallel model)/Reset signal (Serial model), initialization starts after the printer completes printing all the passes of the line that it is printing, and clears the data that remains in the buffer. (This is the spec similar to hardware reset.) Presence of unprocessed data does prompt print start. (2) Reception of I-PRIME signal (Parallel model)/Reset signal (Serial model) in Dump Mode prompts printer initialization, but Dump Mode continues. (3) Initialization prompted by reception of I-PRIME signal (Parallel model)/Reset signal (Serial model) does not prompt local test or menu startup; in other words, the press of the switch is all disabled during initialization. (4) If Slip is already loaded, paper eject is performed according to the sensor monitoring, and initialization starts after removal of paper. (5) During recoverable alarm (including the state in which removal of paper is awaited), initialization is put on hold. After alarm has been cleared (or after removal of paper), initialization starts. While initialization is put on hold, the Parallel model is disabled to receive (because Busy signal is at High), but the Serial model reads data into receive buffer and executes only DLE EOT n, GS ENQ, DLE EOT BS n, ESC DLE r Pno n. (Data read into the receive buffer is cleared in the initialization process.) (6) If Validation is already loaded, initialization starts after removal of paper. (7) With the option tractor installed and the lever set to Tractor, when the status is Slip Sensor Paper End and Validation Sensor Paper present, even if Sprocket paper has been loaded, Media Mismatch alarm in Receipt+Journal Mode occurs. (8) If the data to be sent to the host PC still remains without being reverse-transferred, that data will be cleared. If the Software Reset command or the Menu Item Set command is received, however, ASB status and Check Paper Read result data (including Re-send Request) is cleared, but status data other than that is kept. (Note) With the hard reset (setting by Short Plug with Parallel I/F board and by DIP SW with Serial I/F board), the same operation as at POW-ON is performed. <<Cautionary notes at reception of Menu Item Set command>> (1) The receive buffer is not cleared. Print data in the print buffer is cleared, prompting initialization of each setting. If receiving lines of data has been completed prior to reception of this command and print start has been already initiated, that data cannot be cleared. (2) If the size of the receive buffer has been changed by the Menu Item Set command, it cannot be changed again until a power cycle takes place or I-PRIME signal (Parallel model)/Reset signal (Serial model) is received. 41049421PS Rev.3 142 / No. Items Settings 1 Print head position Centering position (At Power On: Homing, then centering) 2 Horizontal direction print position (Left margin position) The first dot position (Column 0) 3 Print position alighment set Left alignment 4 Line feed pitch 6LPI(all print sheets) 5 International character set American 6 Character code table USA 7 Print font By Menu settings 8 Character right-side space 0 dot 9 Underline designate Reset 10 Double height set Reset 11 Double width set Reset 12 Italic mode Reset 13 Emphasized designate Reset 14 Double strike print designate Reset 15 Print sheet Receipt+Journal (Sprocket paper if print sheet is present and the lever is set to Tractor when the option tractor is installed.) 16 Set sheet All sheets are valid. 17 Print stop sensor select Receipt End Sensor and Journal End Sensor are valid.

The IEEE1284 defines the following signaling methods: (1) Compatible mode (Compatibility mode) (2) Nibble mode (3) Byte mode (4) ECP mode (5) EPP mode This printer supports IEEE1284 compliant bi-directional Centronics interfaces. Of these five modes, this printer supports “Compatible mode” and “Nibble mode”. (1) Compatible mode This mode is compatible with standard Centronics interface (36pin parallel I/F). Data goes from the host to the printer unidirectionary. This mode will be the default mode of the IEEE1284. (2) Nibble mode This mode makes the data transfer from the printer to the host possible when the host requests it. When the printer sends data to the host, it uses the status line from the printer to the host, and sends 1byte data to the host by transferring 4bit data per transfer, twice. Next several chapters describe details of the interface including each of the above modes. 41049421PS Rev.3 153 /

Compatible mode transfers data in parallel using the 8-bit data lines. As described earlier, this mode is the default mode in the IEEE1284 interface, and after the power to the printer is turned on and the printer is initialized by the nInit (I-PRIME) signal, the printer will always be in this mode. In the compatible mode, the host can select from the following operations: (1) Forward transfer (host → printer) by parallel interface in the compatible mode (2) Starting negotiation phase to shift to the mode that enables reverse transfer (printer → host), from the compatible mode. The following table shows the names and the functions of the signals used in this mode: Names Pin No. 2~9

Compatible Mode Handshake The handshake in the compatible mode has the following two phases: (1) Forward data transfer phase This phase is the forward transfer phase that begins when the host outputs nStrobe signal “Low” pulse. The host can begin this phase any time from the forward idle phase status. The forward data transfer takes place in the following manner:

(Host) (Host) (Printer) (Printer) (Printer)

Outputs data to transfer to the printer on the 8-bit parallel line(s). Indicates that that data is valid by setting nStrobe signal Low . Latches the data and sets the Busy signal High . Decodes the received data and prepares to receive next data. Sets Busy signal Low , returns nAck signal to the host and informs the host that it can receive next data. Shifts to the forward idle phase. Forward idle phase This phase indicates that data transfer is not taking place in the compatible mode, and the host can begin the forward data transfer phase or the negotiation phase to request the shift to other mode. In this phase, the printer can set Busy signal “High” at an arbitrary timing, and inhibit the forward data transfer phase. Compatible mode handshake timing chart

Negotiation phase start Next chapter (Chapter 4.4) describes how the negotiation phase can be started, its method and details. 41049421PS Rev.3 157 /

When it requests information such as the device ID from the printer, the host tries to switch the mode to the one which can transfer data in reverse (printer → host), from the compatible mode. Here, the phase to select the most appropriate mode out of the transfer modes supported by both the host and the printer and switch to that mode is called Negotiation Phase.

Details of Negotiation This section describes the details of the negotiation when the host requests to shift to other mode from the compatible mode. The table below shows the names and the functions of the signals used in the negotiation phase: Pin No. Names Direction Traditional Compatible mode

(1) (2) (3) Negotiation and handshake 1284 mode switch request When it requests the reverse transfer from the printer, the host places the 1 byte extensibility request value on the data line as the request to switch to the reverse transfer possible mode from the compatible mode, sets the 1284 Active signal “High” at the same time setting HostBusy signal “Low”. Response status set For the 1284 mode switch request, if it supports the requested mode, the printer sets the response status that includes AckDataReq signal and nDataAvail signal “High” settings, to indicate that it is IEEE1284 compliant. When there is no response (the printer is not IEEE 1284 compliant), the host withdraws the 1284 mode switch request and returns to the compatible mode and forward idle phase. Switch Mode provision With the above response status returned, the host acknowledges the support of the IEEE1284 by the printer and shows the extensibility request value (shown below) to the printer by setting HostClk signal “Low”.

Nibble Mode is the mode for the printer to transfer the information such as Device ID that the printer has to the host (reverse transfer), in response to the request from the host. This mode is started by the negotiation from the Compatible Mode, and after Power On and the initialization by nInit (I-PRIME) signal, the printer never starts in this mode. In the Nibble Mode, the host can select from the following operations: (1) Asynchronous reverse (printer R host) transfer in the Nibble Mode (2) Starting the termination phase to return to the Compatible Mode from the Nibble Mode The table below shows the names and the functions of the signals used in this mode: Pin No. Name Direction Function HostClk Data bit1~8 PtrClk From Host From Host To Host BUSY PtrBusy To Host

Nibble Mode Handshake Handshake in the Nibble Mode has the following phases: (1) Host busy data available phase When the printer has data to send to the host after the negotiation to the Nibble Mode has ended or 1byte data was sent, the transition to this phase takes place. In this phase, the transition to the reverse data transfer phase takes place when HostBusy signal becomes “Low”. (2) Host busy data not available phase Shifts to this phase when there is no data to send from printer to host after the negotiation to the Nibble Mode ends or 1-byte data is sent If data to send becomes available in this phase, the phase shifts to Nibble mode host busy data available phase. (3) Reverse data transfer phase This phase performs asynchronous reverse data transfer that is activated when HostBusy signal becomes “Low”, from the host busy data available phase. Data transfer is done in the following manner:

(Printer) (Host) (Printer) (Host) (Printer) Sets PtrClk signal “Low” to indicate that data is valid. Latches data and sets HostBusy signal “High”. Acknowledges HostBusy signal “High” and sets PtrClk signal “High”. Sets HostBusy signal “Low” to indicate that it can accept high order nibble data. Places bit4 ~ bit7 of the transfer data on nDataAvail, Xflag, AckDataReq & PtrBusy signals.

(4) (5) (6) Nibble mode/host busy data available phase Sets HostBusy signal “Low” to indicate that it can accept low order nibble data. (Nibble Mode reverse data transfer begins.) Sets PtrClk signal “Low” to show host that data is valid. Latches data and sets HostBusy signal “High”. Acknowledges HostBusy signal “High” and sets PtrClk signal “High”. Shifts to host busy data available phase or host busy data not available phase. Reverse idle phase This phase means: No reverse data transfer is in progress, there is no reverse transfer data, either, and HostBusy signal is “Low” (host can start receiving reverse data). If transfer data becomes available in this phase, the phase shifts to host busy data available phase. Interrupt phase This is a phase that provides the mechanism for the printer to alert the host that it has data to transfer, in the reverse idle phase. Printer shows host that it has data to transfer by setting nDataAvail signal “Low” and outputting PtrClk signal “Low” pulse, and prompts host to get ready to receive the data. Phase shifts to host busy data available phase via this phase. Nibble mode termination phase Termination phase is a phase to return to Compatible Mode from the Nibble Mode by the host’s reverse transfer termination (Nibble Mode) request. This phase is activated when 1284 Active signal becomes “Low” and HostBusy signal becomes “High” from the valid state. 41049421PS Rev.3 165 / 41049421PS Rev.3 PtrClk (nAck) PtrBusy (Busy) AckDataReq (PError) XFlag (Select) nDataAvail (nFault) HostClk (nStrobe) HostBusy (nAutofd) Data 1 ~ 8

Host can request the device ID at an arbitrary timing from Compatible Mode/forward idle phase. This printer returns the device ID in Nibble Mode.

Device ID Format The device ID is composed of 2 bytes that indicate the data length of the ID data and key and value combination shown below. key:value{,value}; As seen above, one key takes more than one value. The minimum required keys are MANUFACTURER(MFG), COMMAND SET(CMD) and MODEL(MDL). You can set a key(s) other than these three. Keys and values are character strings and you can use characters other than a colon (:), a comma(,), semi colon (;). Space (20H), tab(08H), vertical tab (0BH), carriage return(0DH), line feed(0AH) and form feed(0CH) are included in the character length, but host ignores them (does not recognize). (1) Device ID byte length The first 2 bytes of the device ID indicate the length of the device ID string that includes these 2 bytes (Byte 1 is high order byte while Byte2 is low order byte). Host returns to the Compatible Mode regardless of whether additional data to transfer is available or not when it receives all the data of the device ID byte length shown here. If the host returns to Compatible Mode before it receives all the data, the printer discards the data that has not been sent, and sends from the Byte1 of the device ID if the data is to be resent. (2) MANUFACTURER Indicates the name of the manufacturer. (3) COMMAND SET Indicates command(s) that can be used. (4) MODEL Indicates the device model. (5) Others Indicates comments or emulation that is currently in use. ← In this printer, ROM revision and factory option are added as a comment. 41049421PS Rev.3 184 /

In other words, no re-send control is performed. 41049421PS Rev.3 185 /

4.8 NIBBLE MODE REVERSE CHANNEL TRANSFER

Reverse channel transfer data In response to the aforementioned “Nibble mode reverse channel transfer request”, this printer notifies host of the following information:

• ASB : Automatic Status Back Depending on the printer’s status change, this function automatically notifies host of the status. There are two ASB status: 4 byte 1 set (GS a) and 5 byte 1 set (ESC DLE a) Description in this document is based on “4 byte 1 set (GS a).”

Transfer priority of reverse channel transfer data Reverse channel transfer data is given priority depending on its data type, and transferred. The following shows priorities of each transfer data. High ← Priority → Low MICR read data > ASB > Real time commands/non-real time commands

• Real time commands: Non-real time commands: Commands processed at receive (When stored in receive buffer)(DLE EOT etc.) Commands processed at decode (When receive buffer is read)(ESC v etc.) (Example) When a response by status request command and ASB data coexist as follows, (1) Status request command 1 (GS r and etc.) → Response is S1 (1 byte). (2) ASB applied status change 1 (S sensor change and etc.) → Response is ASB1-1 - 1-4 (4 bytes). (3) Status request command 2 (GS r and etc.) → Response is S2 (1 byte). If no reverse transfer is performed during (1) - (3), reverse transfer data will be as follows. (According to the above priorities) 41049421PS Rev.3 Byte 1 Byte2 Byte 3 Byte 4 Byte 5 Byte6 ASB 1-1 ASB 1-2 ASB 1-3 ASB 1-4

Error control while reverse channel transfer data is being transferred The following shows an error control depending on the transfer data type, while reverse channel transfer is being transferred.

Control when status other than ASB is being transferred When there are 3 sets (3 bytes) of status data as below, Byte 1 Byte 2 Byte 3

When transfer is interrupted (aborted, terminated) while Byte 1 is transferred. Byte 1

• Aborted or terminated (When reverse transfer is re-started) Byte 1 Byte 2

• Data that was interrupted during transfer is not re-sent. (If the data is aborted after the lower nibble is transferred (case in Chapter 4.6.1(3) - (5)), the data is not re-sent and discarded.)

Control when ASB is being transferred When there is a set of ASB data (4 byte) as below shows, Byte 1 Byte 2 Byte 3 Byte 4 ASB 1-1 ASB 1-2 ASB 1-3 ASB 1-4 (When transfer is interrupted (aborted, terminated) while Byte 2 is being transferred) Byte 1 Byte 2 ASB 1-1 ASB 1-2

• Aborted or terminated (When reverse transfer is re-started) Byte 1 Byte 2 Byte 3 Byte 4 ASB 1-1 ASB 1-2 ASB 1-3 ASB 1-4

• Re-sending starts at the Byte 1 of the ASB data string (4 bytes, 1 set) whose transfer was interrupted. 41049421PS Rev.3 187 /

Control while MICR read data is being transferred When there is 1 set (n byte) of MICR read data (transfer sequence) Byte 1 Byte 2 Byte 3 Byte 4

MICR-n (When transfer is interrupted (aborted, terminated) when Byte 2 is being transferred) Byte 1 Byte 2 MICR-1 MICR-2

• Re-sending starts at Byte 1 of the MICR read data (transfer sequence) whose transfer is interrupted. 41049421PS Rev.3 188 /

Control while ASB/non-ASB mixed data is being transferred When response by status request command (S1, S2) and ASB data coexist as the below shows, Byte 1 Byte 2 Byte 3 Byte 4 Byte 5 Byte 6 ASB 1-1 ASB 1-2 ASB 1-3 ASB 1-4

If the following status change occurs after the transfer is interrupted while the above status is being transferred,

• ASB applied status change (S sensor change or etc.) → Response is ASB2-1 ~ 2-4 (4 bytes) the transfer data responding to the next reverse data transfer request will be as follows depending on the data type of the interrupted data. (a) When interrupted while ASB1-1 ~ ASB1-4 is being transferred, Byte 1 Byte 2 ASB 1-1 ASB 1-2

This printer is initialized at Power On and when the nInit signal “Low” level is received. This chapter describes the interface initialization that accompanies the above initialization and the start of handshake that includes the negotiation after the initialization ends.

I/F Signals During Initialization The I/F signals’ statuses during this printer’s initialization operation and the timing chart for the 1284 mode negotiation to become valid are shown in the diagram below: (1) Initialization by Power On Status established Pow On Output stable Select PError 1284 negotiation valid

• The above diagram shows the timing chart at Power On in the normal state.
• The signal statuses and the timing chart may change depending on the circuit and the process.
• The time from Power On to the establishment of the status varies with the position of the head and the platen and other factors at the time of Power On. 41049421PS Rev.3 190 / (2) Initialization by nInit signal 1284 negotiation 1284 negotiation Status established invalid valid

This specification document describes the detailed specifications of RS-232C serial interface reception that is realized by the firmware.

Receive Buffer Size There are two sizes for the receive buffer that can be selected in the printer’s menu setting item “Receive Buffer Size”, as shown below: (1) 2Kbyte (2) 16Kbyte

Receive buffer structure In the receive buffer, “Receive Buffer Near Full Area” and “Receive Buffer Full Area” are set, and each area is 256byte. The Receive Buffer Near Full Area is the area that indicates that the number of data bytes that can be stored in the receive buffer is 256byte or more, but less than 512byte. And if data enters this Near Full Area, the control shifts to receive data for every 700ms. The Receive Full Areas is the area that indicates that the number of data bytes that can be stored in the receive buffer is down to less than 256byte. When data enters Buffer Full Area, the Receive Buffer Busy state is maintained, and sending data from the host machine is prohibited. For the details of the Receive Buffer Busy control that is executed when storing receive data, refer to Section 4.5, “Protocol”.

5.3 Selecting a Function

You can select various functions by DIP switch installed on the RS-232C interface board. When you change a setting by DIP switch, turn off the printer, change the setting and then turn on the printer again.

Receive data error check The below three receive data errors are checked. Receive data error check is performed only when DIP switch 2-3 setting is set to “OFF.” When DIP 2-3 switch is set to “ON,” receive error is not checked. (Data is output as it is received.)

Parity check This is a function that calculates the total of “1” (MARK) of each bit of the received data (including Parity bit), and checks whether the status of even number/odd number agrees with the Parity mode selected by DIP switch 1-3. When DIP switch 1-2 is set to OFF, parity check is not performed. MARK DATA Data

SPACE STOP bit START bit The bit number of data bit and parity bit in 1 status should be an even number or an odd number. (Start bit and Stop bit are not included.)

DSR signal when data is being received Printer does not control receive data valid/invalid according to the status of DSR signal when receive data is received. It receives the sent data regardless of the status of DSR signal. Even though protocol is set either XON or XOFF, the received data is valid regardless of the status of DSR signal. SPACE DSR signal MARK MARK RXD signal Data A Data B Data C SPACE The received data sent by host is valid regardless the status of DSR signal. Figure 5.13 DSR signal and receive data

DSR signal when data is being sent When host machine returns a response to printer’s status read command, the status of DSR signal is monitored only in the case of the commands described in Chapter 5.3.4.3. When DSR signal is in MARK status (“1”), a printer does not send a response data to host machine. SPACE DSR signal MARK MARK RXD signal Status request A Status request B SPACE SPACE TXD signal MARK Sends response data to status request A command. Because DSR signal is in MARK status, response data to status request B command is not sent. Figure 5.14 DSR signal and printer status response data 41049421PS Rev.3 207 /

Printer status request command that monitors status of DSR signal As described above, the below commands check DSR signal when response data to printer status request command is being sent. If DSR signal is in MARK status when response data is being sent, response data is not sent. Table 5-5 Printer status request commands that monitor DSR signal No. Command

Printer status request command when DSR signal is in MARK status Printer status request command that could not be sent because DSR signal was in MARK status is not discarded. When DSR signal shifts to SPACE status, response data is sent to host machine. A printer status request command can store response data that can be stored in receive buffer at maximum. When printer status request command that cannot be stored in receive buffer is received, the printer status request command is received, but ignored. SPACE DSR signal MARK SPACE RXD signal Status request A Status request B MARK SPACE TXD signal MARK Response data to status request A,B command is not sent. Judges DSR signal status when response data is sent. Because DSR signal shifted to SPACE status, sends response data to status request A and B command. Figure 5.15 Printer status request command and status response when DSR signal is in MARK status 41049421PS Rev.3 209 /

Protocol You can select two types of protocols by switching DIP switch 1-4. Protocol Ready / Busy X-ON / X-OFF

Ready / Busy protocols Ready / Busy protocol notifies printer’s Busy/Ready status to host computer by DTR signal cable (20pin). (1) Busy control This control checks remaining receive buffer and makes sure that all the data is received by controlling data receive available/not available, using DTR signal cable. (2) Busy status display When remaining receive buffer becomes 512 byte or less, Busy control signal shows Busy status, and requests host to stop data sending. The timing when buffer remaining recovers to 512byte or more is within 200ms after Busy ON, Busy control signal becomes Ready status in 200ms. If it is not within 200ms, Busy control signal becomes Ready status when the buffer recovers to 512byte or more.

• The minimum Busy On time, 200ms is program’s fixed value. (3) Timing chart RXD signal DATA DATA MAX Receive buffer Remaining byte 512byte 256byte 0byte

X-ON / X-OFF protocol This protocol sends printer’s Busy / Ready status using the below function codes and notifies host computer. The following is the function codes that can notify Busy / Ready status. Command DC1 DC3 Hex

Function Sends when printer shifts Busy → Ready status. Sends when printer shifts Ready → Busy status. (1) Busy control This control checks remaining buffer, controls data receive available/not available using the above function codes, and receives data without ignoring it. (2) Busy status display When receive buffer remaining becomes 512byte or less, returns DC3 code, and notifies the sender that receiving is not possible. If receive buffer remaining recovers to 512byte or more within 200ms after DC3 code return, returns DCI code in 200 ms, and notifies the sender that receiving is possible. If receive buffer remaining recovers to 512 byte or more after 200ms of DC3 code return, returns DCI code when the buffer recovers to 512 byte or more. (3) DTR signal when X-ON/X-OFF protocol is selected DTR signal when X-ON/X-OFF protocol is selected always should keep Ready status (SPACE). However, a printer experiences an irrecoverable alarm for some reason, DTR signal should be in Busy status (MARK). (4) Timing chart RXD signal DATA DATA

Busy On timeout receive control Due to Busy On timeout control, host computer may become send timeout when Busy status continues for a long time of period without being canceled. To avoid timeout, this function regularly (every 700ms) cancels Busy status and receives 1 byte data even though receive buffer is in near-full status.

Behavior This Busy On timeout receive is controlled by Busy ON timer (200ms) and 700ms timer. The following shows behaviors of each timer at the time of timeout. Busy timeout condition Receive buffer remaining Only 200ms timeout occurs 512Byte or more 511 ~ 256Byte 255Byte or less 200ms timeout and 700ms 512Byte or more time out occur 511 ~ 256Byte 255Byte or less Function Cancels Busy Keeps Busy status Keeps Busy status Cancels Busy 1Byte receive Keeps Busy status When receive buffer size that can store data becomes 511(256byte, cancels Busy status in every 700ms, and receives 1 byte data. When 1 byte data is received, immediately resumes Busy status, and requests data sending stop. When receive buffer size that can store data becomes less than 256byte, stops data receive in every 700ms. Resumes data receive, when buffer remaining becomes 256byte or more. 41049421PS Rev.3 212 /

Custmer display This printer is ready for connection of customer display. Customer display connection becomes available when DIP switch 1-8 is set to ON. RS-232C interface control enables host machine to sense Busy status of customer display. Thus, H/W executes output control of the status by using RTS signal cable.

Customer display connection and RTS signal RTS signal that a printer outputs OR status of the printer DTR signal and customer display DTR signal instead of outputting DTR status of customer display as it is. (See the below diagram.) When DIP switch 1–8 is set to OFF, printer’s DTR signal is output to RTS signal as is.

Customer display connection/non-connection and RTS signal status The below table shows RTS signal status output by the circuit described above.

Printer reset signal This printer has reset signal so that host machine can initialize the printer even though RS-232C interface is in use. There are two lines of reset signals, DSR signal (6 pin) and INIT signal (25 pin). You can select valid/ invalid by DIP switch 2 -1 and 2-2. When the reset signal is set to valid by DIP switch 2-1 and 2-2, you can initialize the printer by inputting reset pulse over 100 µs from host. There are two printer initializations. (1) (2) H/W reset (Same as POWER ON) F/W reset You can select either by DIP switch. (Factory shipment setting is F/W reset.) When F/W reset is selected, H/W inputs reset pulse signal to I-PRIME signal of Centronics interface. Thus, the same initialization as the I-PRIME signal of Centronics interface is performed.

Printer Busy control when reset signal is received Printer becomes OFF-LINE when reset signal is input, and DTR signal and RTS signal shift to Busy status (MARK). Even though protocol is set to X-ON/X-OFF, DTR signal and RTS signal shift to Busy status by reset signal input. The printer does not start initialization until the reset signal is canceled.

Busy control in X-ON/X-OFF protocol If reset signal is input when protocol is set to X-ON/X-OFF, Busy control in H/W reset and Busy control in F/W reset are different.

In case of H/W reset, DC3 code is not output immediately even though reset signal is input as the below shows. Reset signal canceled Power on and initialization end OFF Reset signal 100us or more SPACE RTS signal MARK SPACE DTR signal MARK TXD signal

Outputs DC3 code at Power on and at initialization start Figure 5.25 X-ON/X-OFF control in H/W reset > DC3 code is output when reset signal is canceled and initialization starts. The time between reset signal ON and RTS/DTR signal shift to MARK status (Busy status) is not decided yet. When decided, will be clearly described. 41049421PS Rev.3 220 /

In case of F/W reset, the program recognizes reset signal input and executes reset. Busy control data (DC3) is output at the time when reset signal is input, which is different from the case of H/W reset.
