If the printer appears to have communication problems, the self-test configuration test labels and character hex dump modes should be checked. The tests can help identify printer configuration errors that can cause problems.

Both of these test procedures are covered in this chapter. Configuration items to check include the following:

Check that the data string being sent to the printer contains the correct information.

Verify that the correct host interface port is being used and that the communication parameters match those of the host (i.e., baud rate, parity, etc.).

Verify that the correct interface cable is installed between the host and the printer.

Interfacing

The printer will not function properly with an incorrectly wired cable or the wrong interface cable installed. If the cable is suspect, contact Printronix or your authorized service representative.

When the printer is first powered up, it will reset itself to the communication default parameters. The parameters are listed in Table 4±1.
