Hi @chazzy1,

Welcome to the HP Support Community

I understand you are facing a print quality issue with your HP OfficeJet Pro 6978 All-In-One Printer. Not to worry I will help you to get a resolution to resolve the issue.

To assist better:

• Are you using genuine HP ink cartridges?
• Does the copy print out the same way? 
• Are you enrolled in the HP Instant Ink program?
• Where did you order the inks from?
• 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 -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 to 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.
