Hi @Rodrob,
I'd like to help!
To better assist you -
1) Does the copy print out the same way?
2) What's the application you are trying to print from? Have you tried printing from a different application or device?
While you respond to that, let's print a Print Quality Diagnostic page -
-
Load plain white paper in the tray.
-
Print the report.
-
Printers with a touchscreen or menus: On the printer, open the Settings
or Setup menu, touch Tools or Reports, and then touch Print Quality Report or similar.
Post the Print Quality Diagnostic page here so we can help you further.
You may also refer to this document with steps to fix the " Print Quality Issues" issue applicable for your printer - Print Quality Issues
Also, try updating the printer's firmware - HP Printers - Updating or Upgrading Printer Firmware
Hope this helps! Keep me posted.
