My printer works but prints nonsense

[Larbear57]

HP Officejet 8620

It printed the demo page perfectly.

I tried to print a page from my MacbookPro Apple Laptop but what printed was nonsense, just some patial lines and first time I tried a partial printout of my ink cartridge status.

@Larbear57, Welcome to HP Support Community!

Let us try to isolate the issue first. Here is how you do it-

Print a Print Quality Diagnostic Page to identify the print quality issue.

1. Load plain white paper into the tray.

2. On the printer control panel, swipe the display to scroll to Setup, and then touch the Setup icon (). The Setup menu displays.

3. Swipe the display to scroll to Print Reports, and then touch Print Reports.

4. Touch Print Quality Report. The printer prints a test page.

Ensure that the printer is up to date with its firmware and Mac is up to date with its software. If you are unsure you may use the links below to update the printer firmware and Mac software:
