How can I fix '"HPDM.framework" will damage your computer' on macOS Big Sur?

Solution 1:

After much trial and error, I was finally able to get my HP DeskJet 1010 printer working again with the following steps:

1. Download and run the HP Uninstaller app
2. Download and install HP Printer Drivers v5.1 for macOS
3. Open 'System Preferences' -> 'Printers & Scanners', right-click the box labeled 'Printers' and select 'Reset printing system...' (if you have more than one printer, you may want to remove just the non-functioning profile by selecting it and clicking the '-' button).
4. Click the '+' button to add a new printer, select 'HP DeskJet Series', and follow the prompts.

It is my suspicion that this will work with other HP printers affected by their revoked developer certificate.
