Verifying Printer Communications With Your System

After connecting the printer to your system, you need to test communications.
The easiest way to test communications is to set the printer to Data Line Print
mode, which is part of Test and Service mode, and send a character string
down from your system.
If you have just printed a configuration test label, you are already in Data Line
Print mode. Start the following procedure with Step 4.
Note: Make sure that your cabling is correct. See Appendix B, "Cabling and
Communications," for more information. If your cabling is not correct, you may receive
a write fault error.
To verify communications with your system
1. Turn the ON/OFF switch to the off position.
2. Press and hold the Feed/Pause button while you turn the ON/OFF switch
3. Release the Feed/Pause button. You are now in Data Line Print mode.
4. Transmit at least four characters from your system.
5. To enter normal Print mode, turn the printer power off and then on again.
If this procedure does not work, make sure that the DIP switches match the
serial port configuration of the system. Make sure you have the printer cable
securely plugged into the correct port of your system.
to the on position. The printer prints out the hardware configuration test
label.
At this point the printer does not attempt to interpret any printer
commands, but simply prints each character with its hexadecimal
equivalent underneath.
