CANNOT USE THE SCAN FUNCTION.  I GET THIS MESSAGE 

Software for “%@” failed to run.

HOW DO I SOLVE THIS ISSUE?

I also have the same issue that happened overnight. The pop-up says software for "%@" failed to run. (-9927) I have an IMac running Catalina and a Macbook Pro running Mojave. To make my life more efficient I also have three HP Officejet Pro 8600 printers I paid big $$$ for when new. I like having to only stock one size ink cartridges.  I can print just fine but trying to use the scan function from the computers is bricked. Printing and all other communication (i.e. ink levels) work fine. I reset the printer system and reloaded all printers individually even not using Airprint and selecting the HP 8600 drivers after updating the most recent drivers from HP. The scan function is still bricked. Dusted off an old Macbook running El Capitan and the scan function works just fine. Looks like either Apple or HP automatic upgrades just bricked the scan function on my three very expensive printers. I use my scanning function almost daily.

I recieved notice from AppleInsider that HP security certificates may have expired and Apple OS is calling it malware. These two goliaths need to get this worked out pronto.
