Interfacing - Printronix T3306 Setup Manual

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.
Table 4–1. Printer Default Communication Parameters
The printer configuration settings may be entered through the main menu HOST
INTERFACE function, which is accessed through the secondary control panel.
