Poor picture printing but only on 8.5x11. 4x6 in bottom tray are fine.

I have changed the ink cartridge. Run all the diagnostic options. They're all fine. I was printing out Christmas cards pictures on 8.5x11 photo paper and the quality slowly got worse and worse. Printing pictures in the bottom tray 4x6 are fine. Printing the pictures on regular paper are fine. Trying to print on the same paper that the earlier copies were fine, are terrible. Color is off and there's horizontal lines all over.

@EForbess, Welcome to HP Support Community!

I'd suggest you follow the steps from the document Black or Color Ink Not Printing, Other Print Quality Issues to isolate and resolve the issue.

Also, Update the printer firmware

Download available firmware updates from the HP website

With the printer on and connected to the computer, go to HP Customer Support - Software and Driver Downloads, and then identify your printer. Look for and install any available firmware updates. Refer to the document HP Printers - Updating or Upgrading Printer Firmware

Hope this helps! Keep me posted.
