My printer can not be located.

My printer ( hp officeJet pro 8720) stopped working. I'm getting a message every 10 seconds and will not go away that says "HPDM. framework will damage your computer." I've reinstalled driver but that did not help.

The solution is to download (and install) this package (From HP FTP) which will update drivers AND THE CERTIFICATE:
ftp://ftp.hp.com/pub/softlib/software12/HP_Quick_Start/osx/Installations/Essentials/hp-printer-essen...
The install takes a bit. Let it run, even if it seems like it stalled out!

It is NOT the same as the driver package, Easy Start, or Easy Admin other people are recommending.

If the link comes up blank, try right clicking and saving it. If you install this package and still have trouble, try restarting. Then go about uninstalling your printer and reinstalling USING THIS METHOD ONLY: Apple Logo (Upper Left of Screen)/System Preferences/Printers & Scanners. Then restart your computer. 

If you still can't find the printer, install the 5.1 driver package from HP: https://support.apple.com/kb/dl1888?locale=en_US

Then restart and try to install again through the Printers & Scanners menu.

Easy Admin did nothing. Easy Startup did nothing. 5.1 drivers did nothing. This worked for me!

If this solved your issue, please thumbs up and mark as solved!
