Miscellaneous Issues

recommended solutions.

off. Cycle the printer OFF and then back ON to verify settings have been saved.
Possible Cause - 2

errors or have been used incorrectly.
• A firmware command turned off the ability to change the parameter.
• A firmware command changed the parameter back to default setting.

The prefix and delimiter characters set in the printer do not match the ones in the label
format.
Resolution

correct for your system software environment. Print a Configuration Report or use display’s
Language Menu (if present) for these three (3) menu items and compare it the commands
in label format/form you are trying to print. See Test Printing with the Configuration Report,
LANGUAGE Menu, and ZPL Configuration.
