Media and Ribbon Combination.

  • The type of labels and ribbon (if used) impacts the quality of the print. Consult with your supplier for details.

A printer self test label can be used to determine if the given print quality issue is seen from the printer itself and to test any changes made on the printer as you are troubleshooting the issue.

The printer operates at the selected speed in terms of inches/mm per second.  Because print quality is affected by print speed, media, ribbon ( if thermal transfer ), and printer operating modes, it is important to run tests for your application to choose the optimal print speed setting.  Slowing down the print speed can also help if the print is too light.

The ZP450 and ZP500 are shipping vendor specific printers.  Each vendor provides their own software and driver to use with the printer.  Driver settings will override printer settings.  For help configuring each vendor's printer driver see the following links:
