Hi @Rosie

 I'd like to help!

I understand you are facing print quality issues

To assist better-

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 -

1. Make sure to load the input tray with plain, white paper.

2. On the printer control panel, swipe the display to the left, and then touch Setup.

3. Touch Tools.

4. Swipe up on the display, and then touch Print Quality Report.

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.
