Verifying Printer Communications With Your System
Once you have the printer connected to your system, you need to verify that the printer
communicates with your system. The easiest way to test communications is to set the printer to Data
Line Print mode and send down a character string from your system.
If you have just printed a hardware configuration test label, start with Step 4.

Turn the On/Off switch to the off (O) position.
Turn the printer power off and then on again.
Note: An example using DOS to verify printer communications follows this procedure. If this procedure does
not work, check to make sure that the DIP switches are set to the default configuration and that the printer
cable is securely plugged into the correct port of your system.
Release the Feed/Pause button after the hardware
configuration test label prints.
Send down some characters from your system.
At this point the printer does not attempt to interpret
any printer commands. It simply prints each character
with its hexadecimal equivalent underneath.
Press and hold the Feed/Pause button. Turn the
On/Off switch to the on (|) position.

To use DOS to verify printer communications
1. At the DOS prompt, type the following command and press Enter to configure the serial port:
MODE COM1 96,E,7,1,N
2. Type the following command lines and press Enter:
COPY CON COM1
ABCDEF^Z
where:
COPY CON COM1 tells the PC to copy the next line of information to communications port
COM1.
ABCDEF are random characters typed at the host.
^Z (Ctrl-Z) Enter sends the information to the printer.
The printer prints the characters (see step 4 on previous page for example).
Note: If you are using a different platform to communicate with your printer, please refer to your system
user’s manual and the IPL Programming Reference Manual for information on downloading commands.

Note: If you receive a write fault error, your cabling may be incorrect. See “Connecting the Printer to
Your System” earlier in this guide for more information.
