@johno8
Thank you for posting on the HP Support Community.

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:

  • Are you able to make a black and white copy?
  • Are you using genuine HP Ink cartridges or refilled cartridges?
  • Have you tried to print the Print Quality Diagnostic Page?

Let’s first try and make a “photocopy” to determine whether the issue is with the printer or not. Place a document on the scanner glass and choose the “Copy” option. If the printer is making a good copy, then the printer hardware is fine.
 

Hope this helps! Keep me posted for further assistance.
