Hi @Shnapz,
Welcome to the HP Support Community
I understand you are facing a print quality issue with your HP Smart Tank Plus 551 Wireless 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?
- What's the application you are trying to print from?
- What version of iOS is running on your device?
- Have you tried printing from a different application or device?
While you respond to that, let's refer to this document with steps to fix the " Print Quality Issues" issue applicable to your printer - Print Quality Issues
Also, try updating the firmware - HP Printers - Updating or Upgrading Printer Firmware & Update software on iOS
Hope this helps! Keep me posted.
