darkness level.
For optimal print quality, set the darkness to the lowest
possible setting for your application.
1. Perform the steps in Run the Print Wizard and Print
a Test Label on page 52.
2. If necessary, manually adjust the darkness or print
speed settings.
• Set the print darkness to the lowest setting that
provides good print quality. If you set the
darkness too high, the label image may print
unclearly, barcodes may not scan correctly, the
ribbon may burn through, or the printhead may
wear prematurely.
• Slower print speeds typically yield better print
quality.
