3.2.5 Communications Problems
 Note: If troubleshooting an Ethernet or USB equipped printer, refer to the documentation that
accompanied the option.
1. Turn OFF the printer. Ensure an
interface cable is properly
connected between the host and
printer then turn ON the printer.
Send a label format from the host.
Did the label print?
Test completed. If the label format does
not appear as expected, check the label
layout and commands.
2. Are characters printed instead of
the expected label format?
The printer may be in Hex Dump Mode;
disable it (see Section 3.4).
3. Press TEST. Scroll to PRINT
CONFIGURATION and then press
TEST.
Compare the communications
settings listed on the Configuration
Label to the host’s communication
settings. Do the printer and the
host settings differ?
Reconfigure the settings to match. Also, if
using the Parallel Port it may be necessary
to change the printer’s PORT DIRECTION
to bidirectional, as some host computers
await a response.
4. Enable Hex Dump Mode (see
Section 3.4). Send a label format to
the printer from the host.
Does a Hex/ASCII Label print?
Compare printer COMMUNICATIONS /
HOST SETTINGS / CONTROL CODES
setting with the corresponding codes
issued by the host; these must match.
An incorrect or defective
interface cable is being
used.
