when operated at normal room temperature.
1.5 Prepare the Printer for Use
1. Install a roll of thermal paper in paper dispenser by lifting the dispenser cover
and placing the paper in with the thermal side facing outward. Refer to Figure
1.1 for paper dispenser location.
1a. To test which side is thermal, run a fingernail across the paper. A mark should
show on the paper. If no mark appears, try the other side of the paper.
2. With about 1/2 inch of paper sticking out, close the paper dispenser cover.
3. Connect RS-232 cable by plugging the PS/2 end of the cable to the printer.
Refer to Figure 1.1 for PS/2 connector location.
4. Connect AC power adapter to the printer by plugging the adapter connector
into the printer power supply plug. Refer to Figure 1.1 for power input location.
5. When ready, plug the other end of the AC adapter into a wall socket.
6. Plug the RS-232 serial cable in the host device.
7. Press the [POWER] button to turn on the printer.

2 Communication
The CP103 Mini Thermal Printer uses a RS-232 serial interface connection with the
host communication. If a serial port is unavailable on the host device, it is possible to
use a serial / USB converter.
2.1 RS-232 Serial Interface
RS-232 is developed according to the EIA standard asynchronous transmission serial
interface. The specifications are as following:
l Data transmission: serial interface
l Synchronization: asynchronous
l Signal Level: RS-232 level, logic 1:-5.4v, logic 0: +5.4v
l Hardware Flow Control: optional
l Baud rate: 1200 bps to 115200 bps (NOTE: At 1200 baud, continous
printing mode of data sending from Host is not supported)
l Data word length: 8 bits
l Stop bit: 1bit
l Parity: None
The printer self-testing page will show the current baud rate. The default baud rate is
115200bps. Refer to Chapter 3 for details on the Printer Self Test.
2.2 CP103 Printer PS/2 Connector
The following drawing illustrates the PS2 socket pinout located on the CP103 printer.
This connection is used for RS-232 communication with an indicator or computer and
requires the PS2 to RS-232 interface cable (serial cable).
Pin Description
1 TXD - data output
2 no connection
3GND
4 no connection (12V DC- IN is optional)
5 RXD - data input

3 Printer Self Test and Cleaning
With the printer off, press and hold the [POWER] button until the printer begins to print
a self-testing page and then release the [POWER] button.
The page gives specific information regarding version of firmware, interface type, print
speed, default baud rate, etc.
3.1 Cleaning the Print Head
When the printer displays the following symptoms the print head should be cleaned:
l The printer does not print clearly and the thermal paper is good
l The page-test printing is not crisp and clear
l Paper feed is noisy
3.1.1 Steps for Cleaning Print Head
1. Turn off the power to the printer and open the paper dispenser cover. Remove
the thermal paper roll.
1a. If the printer was just printing then wait for the print head to cool down.
2. With a soft cotton cloth dipped in rubbing alcohol (make sure there is no
dripping), wipe the thermal printer head gently and remove any dust or debris.
3. Wait for the rubbing alcohol to evaporate completely and then place the
thermal paper roll back in the printer. Close the paper dispenser cover and
print a test page.
