Frequently Asked Questions - STP-131P SAMSUNG

How do I load paper into the Samsung STP-131P printer?

Open the paper roll cover by pulling it up. Remove any old core, then insert a new paper roll ensuring the paper comes off in the correct direction (as indicated in the manual). Close the cover by pressing the center firmly to avoid mis-loading, then tear off the paper using the cutter.

What do the indicator lights mean on the STP-131P?

The POWER (green) light is on when the printer is on. The ERROR (red) light blinks fast when paper is out, and blinks slowly when the near-end sensor is triggered. Both lights are off when the printer cover is open.

How do I perform a self-test?

Make sure paper is installed. Turn on the printer while holding down the FEED button. The self-test will print the current status (ROM version, DIP switch settings). Then it will pause and print a prompt; press the FEED button to continue printing a character set pattern. It will end automatically and cut the paper.

How do I set the DIP switches on the STP-131P?

The printer has two DIP switch banks. Switch 1 controls baud rate, density, handshaking, and auto feeding. Switch 2 controls auto cut type and parity. Refer to the manual tables for specific settings. Ensure the printer is off before changing switches.

What type of paper should I use?

Use thermal paper rolls with a width of 80 mm, thickness 0.062-0.075 mm, and a maximum roll diameter of 83 mm. The spool inside diameter should be 12 mm and outside diameter 18 mm. Do not use paper glued to the core.

How do I connect the STP-131P to my computer?

Use a parallel (Centronics) interface cable. Ensure both printer and computer are off. Plug the cable securely into the printer's interface connector and tighten the screws. Connect the other end to the computer. For serial models, use a serial cable.

What should I do if the printer is not printing?

Check the power and error lights. If the error light is blinking, the paper may be out or the near-end sensor is triggered. Ensure the cover is closed. Verify the interface cable is connected securely and the computer is sending data. Run a self-test to check printer functionality.

How do I enable hexadecimal dump mode?

Set DIP Switch 2 (sw-7) to ON. Turn on the printer. Run software that sends data to the printer. It will print received codes in hexadecimal and ASCII format. To exit, set DIP Switch 2 (sw-7) back to OFF.

What is the power supply requirement for the STP-131P?

Use only the supplied SMPS adapter. Input: 100-240 VAC, 50/60 Hz. Output: 24 VDC. Do not use any other adapter as it could cause damage or fire.

How do I maintain the STP-131P printer?

Keep the printer on a stable surface and away from moisture. Do not disassemble or attempt repairs; contact your dealer for service. Use only approved accessories. Clean the exterior with a dry cloth. Avoid touching the auto cutter blade.

1-3 Adjustments and Settings

The STP-131 Series is set up at the factory to be appropriate for almost all users. It does, however, offer some settings for users with special requirements.

It has DIP switches that allow you to change communication settings, such as handshaking and parity check, as well as print density.

This STP-131 Series also has a near-end sensor for the paper. This can give you a warning when the paper is almost out. If you find that there is not enough paper remaining on the roll when the paper low is triggered, the Error LED (Red) is turned on.

2. Connecting the cables

Before connecting any of the cables, make sure that both the printer and the host are turned off.

2-1 Connecting the Power Supply

When connecting or disconnecting the power supply from the printer, make sure that the power supply is not plugged into an electrical outlet. Otherwise you may damage the power supply or the printer.

If the power supply's rated voltage and your outlet's voltage do not match, contact your dealer for assistance. Do not plug in the power cord. Otherwise, you may damage the power supply or the printer.

• Make sure that the printer's power switch is turned off, and the power supply's power cord is unplugged from the electrical outlet.
• Check the label on the power supply to make sure that the voltage required by the power supply matches that of your electrical outlet.
• Plug in the power supply's adapter cable as shown below. Notice that the flat side of the plug faces down.

Power Connector Adapter Cable

To remove the DC cable connector, grasp the connector at the arrow and pull it straight out. Make sure that the main unit's power cord is unplugged before you disconnect the DC cable connector.

2-2 Connecting the Interface Cables

You need an appropriate interface cable.

Interface Connector (Serial or Parallel)

• Plug the cable connector securely into the printer's interface connector.
• Tighten the screws on both sides of the cable connector.

4. Roll Paper Installation

NOTE

Be sure to use paper rolls that meet specifications. Do not use paper rolls that have the paper glued to the core because the printer cannot detect the paper end correctly.

4-1 Make sure that the printer is not receiving data; otherwise, data may be lost.

4-2 Open the paper roll cover by pulling it up. You must turn on the printer before replacing the paper roll.

NOTE※

Do not open the print cover while the printer is operating. This may damage the printer.

4-3 Remove the used paper roll core if there is one.

4-4 Insert the paper roll.

4-5 Be sure to note the correct direction that the paper comes off the roll.

O

×

4-6 Close the cover.

NOTE※

When closing the cover, press the center of the printer cover firmly to prevent paper mis-loading.

4-7 Tear off the paper as shown.

5. Self Test

The self-test checks whether the printer has any problems. If the printer does not function properly, contact your dealer. The self-test checks the following:

5-1 Make sure the paper roll has been installed properly. 5-2 Turn on the power while holding down the FEED button. The self-test begins. 5-3 The self-test prints the current printer status, which provides the control ROM version and the DIP switch settings. 5-4 After printing the current printer status, self-test printing will print the following, and pause.

SELF-TEST PRINTING. PLEASE PRESS THE FEED BUTTON.

5-5 Press the FEED button to continue printing. The printer prints a pattern using the built-in character set.

5-6 The self-test automatically ends and cuts the paper after printing the following.

*** COMPLETED ***

5-7 The printer is ready to receive data as soon as it completes the self-test.

6. Hexadecimal Dumping

This feature allows experienced users to see exactly what data is coming to the printer. This can be useful in finding software problems. When you turn on the hexadecimal dump function, the printer prints all commands and data in hexadecimal format along with a guide section to help you find specific commands.

To use the hexadecimal dump function, follow these steps:

6-1 Set DIP Switch 2 (sw-7 = Hex dump mode) of your printer to the ON position.

6-2 Turn on the power of your printer.

6-3 Run any software program that sends data to the printer. The printer will print all the codes it receives in a two-column format. The first column contains the hexadecimal codes and the second column gives the ASCII characters that correspond to the codes.

1B 21 00 1B 26 02 40 40 40	40	. ! . . & . @ @ @ @
02 0D 1B 44 0A 14 1E 28 28	28	. . . D . . . . ( ( (
00 01 0A 41 0D 42 0A 43 43	43	. . . A . B . C C C

• A period (.) is printed for each code that has no ASCII equivalent.
• During the hex dump, all commands except DEL EOT are disabled.

6-4 Close the cover, then the printer enters the hexadecimal dump mode.

6-5 Set DIP Switch 2 (sw-7 = Hex dump mode) of your printer to the off position and then hexadecimal mode is off.
