Trouble with printing on HP Officejet Pro 8620 with Mac Catalina OS 10.15.1

[P-Grammy]

I can't get the front panel screen to respond to a simple copy. Also when I choose the number of copies it jumps all over and ends up at  89 copies and will not go back to even 2 copies. This started after I installed Catalina so I am assuming there is a software update to improve the communication. I tried to download drivers from HP, but no improvement. 

By the way, I a very happy with my instant ink program!

Hi @P-Grammy

Welcome to the HP Support Community. I'd be happy to assist you with the copy issue. 

Let's try these steps to reset the printer - 

1) Take out the cartridges. 
2) Unplug the power cord from the printer & wall. 
3) Wait for 30 seconds.  
4) Plug the power cord back into the printer and wall, ensure the printer is plugged into the wall & not to a surge protector. 
5) Insert the cartridges back into the printer.

Also, try updating the printer's firmware - HP Printers - Updating or Upgrading Printer Firmware

If the issue still persists, try restoring the factory settings to defaults - 

1) From the printer control panel display, touch and slide your finger across the screen and then touch Setup.
2) Touch Tools.
3) Touch Restore Factory Defaults, and then touch Yes.
A message appears stating that the printer defaults have been restored.
4) Touch OK. 

Hope this helps! Keep me posted.
