We found this set of instructions very helpful from an end user perspective. Not all of our Mac end users were familiar with the process so I hope sharing this helps.

How to remove the HP printer driver

Go to System Preferences
Click on Printers & Scanners
Choose your HP printer from the Printers list on the left
Click the minus sign at bottom left
In the Finder, go to ~/Library/Printers/hp
Drag the printer driver to the trash
Go back to System Preferences
Click on Printers & Scanners if it doesn't open at that
Click the plus sign at bottom left and re-add the printer

To go the ~/Library/Printers/hp folder, go to the Finder and choose Go, Go to folder... from the menus. Or press Command-Shift-G.

You need to reload the HP printer/scanner drivers before reinstalling the printers. Be patient, driver v5.1 is a biggy and takes about 10 min to install.

I followed your advise and uninstall the printer with HP easy start and re-installed again and it's working again!!! I've lost so much time with hp support (chat and phone) for nothing! HAHAHA

THANKS JanetB58!!!

I deleted and then reinstalled and was able to print but got different message this time: "matterhornframework"

any advice?

I suggest deleting the entire HP folder from the ~/Library/Printers folder. Then download and install the Apple printer drivers via https://support.apple.com/kb/DL1888?locale=en_US

Regarding the matterhornframework error, I found this article with more information:

https://eclecticlight.co/2020/10/23/why-have-my-hp-printers-stopped-working-how-to-check-their-softw...

They are suggesting using Easy Start

Step 1:
Delete the HP printer from System Preferences/Printers and Scanners

Step 2:
Download HP Easy Setup: https://123.hp.com/us/en/devices/setup
Open it, but don’t run it (you should see the HP logo and “welcome to HP Easy Start”.
Go to the top left, click on “HP Easy Start” menu (next to the apple menu), and select “Uninstall HP Software”
Uninstall it all!
Restart
(Video here: https://www.youtube.com/watch?v=EZNvRqQUMzE )

Step 2:
Copy and paste this into the URL in your browser: http://ftp.hp.com/pub/softlib/software12/HP_Quick_Start/osx/Installations/Essentials/hp-printer-esse...
(it might work if you just click on it)
Run the HP Essentials program.. it does take a while, (don’t worry if it looks like it isn’t doing anything for a while)
Restart

Step 3:
Use the HP Easy Setup you downloaded in step 1 to reinstall your printer

I had the very same problem. Apple Support directed me to this solution

https://h30434.www3.hp.com/t5/Printer-Wireless-Networking-Internet/PDE-plugin-will-damage-your-comp...

Deleting the printer and then reinstalling it has worked for me. I can now print and I get no pop-ups about any HP drivers.

Confused48 · ‎10-30-2020

Worked like a charm! Thanks bunches.

Bonita24 · ‎11-01-2020

need help to solve this

johnrwish · ‎11-01-2020

update your printer driver...

it's painless and works!

Confused48 · ‎11-01-2020

I received some great support from other users, which I've pasted below. The first one from "am3b" worked, but if not try the second, longer one from "xavpctech01". (Too bad you can't print it out to follow the script.)

There are other good suggestions on the support group, that have come up since I first had the problem. They all involve deleteing and re-adding your printer. It ended up being easier than I anticipated.

Good luck!!
