My HP printer suddenly went into pause mode recently and I was unable to rectify the problem. I then removed the printer and tried to re-install it however I now get messages to state that the software associated with the printer will damage my computer and I am unable to install the printer.
Does anyone have any similar issues or suggestions to re-install the printer?
iMac 27″, macOS 10.15
Here are the scoop and instruction on how to fix the HP printing issue.
-----------------------------------
From sources familiar with the matter, HP Inc asked Apple to revoke its printer driver code-signing certificates. It appears this request backfired as it left users unable to print. An HP Inc spokesperson said on Friday night:
We unintentionally revoked credentials on some older versions of Mac drivers. This caused a temporary disruption for those customers and we are working with Apple to restore the drivers. In the meantime, we recommend users experiencing this problem to uninstall the HP driver and use the native AirPrint driver to print to their printer.
HP supplied a new driver on Friday to fix the issue:
ftp://ftp.hp.com/pub/softlib/software12/HP_Quick_Start/osx/Installations/Essentials/hp-printer-essentials-S-5_14_8_4.pkg
However, that "fix" is producing this error for some users:
"Matterhorn.framework" will damage your computer…
If you're seeing that, try this fix. Go to System Preferences, select Printers and Scanners. Select your printer from the list then delete (-) it. Then add (+) your printer back and select the generic driver to use.
Update: HP Printer Software 5.1 should now be becoming available through Software Update to fix this issue.

Open >System Preferences>Software Update (Command R will reload and do a fresh check)
If you don't see it there, Apple now has it posted as a separate, manual download.
