HP Utility fails with Code Signature Invalid MacOS 10.15.7

[Hank79]

I gave up! Getting an HP printer, that was working to stop with 10.15.7  and then having to read countless solutions that do nothing but waste time is over for me!  I Disconnected my HP C8180, removed it from my printers on my mac and connected another vendors printer to my MAC and hit the plus sign to add and it and worked IMMEDIATELY! Works perfectly. When apple and HP get their duck in a row again, I may go back to the C8180. Or switch to Win 10! "Apple and HP problems are not mine to solve doing special workarounds!"

Thanks for this, I did something similar but I was so mad I just looked up "HP" in my search and deleted anything and everything that was to do with HP.

Searched for Printer, 

"+" Add printer 

selected mine and it loaded a new upgrade and worked.

Shouldn't be so hard, tried everything prior, even uploading from the HP website the new version.

Anyway, all good now it is working, yay!

Thanks

And last night I remembered my vintage c8180 HP printer is Bluetooth capable! I enabled bluetooth, Turned on bluetooth on my Mac, got it connected and "IT WORKS", I ALSO HAVE A

ANOTHER PRINTER BRAND CONNECTED JUST TO BE SURE!. OTHER PRINT BRANDS WORK FINE! WHAT A MESS!

II fiddled and fiddled with the HP 5.1 download and loading and removing and adding my hp printer till I was blue in the face and getting very frustrated! What I then did, was to get all printers off my mac with the (-) sign, then downloaded 5.1, again, clicked on the (+) and got my c8180 to show up and then did the reload of 5.1 again and then just let the darn thing sit overnight! I did not try and print anything. Got up early checking on the elections and put up a word file, selected my C8180 to print and bingo, off she went. It is my opinion, not being a Mac geru, that somehow during the night since I have selected auto updates, that some code got sent. Apple has been kind of mum on the situation  created by HP that got a bunch of vintage printers providing random ransomware messages. I share this printer via wireless with both Apple and Microsoft based laptops and the only ransomware messages were banging out of my Mac. All is well now, at least for me!

Please fix the HP Printer issue with the MacOS.  I get a message that states some type of component from HP will damage my computer.  Unable to print anything at this point in time!  So frustrating.  Please get this fixed.  Some people are still working and need their printers to work as well.

I fixed it by deleting the printer within System Preferences and reinstalling it, this time selecting the generic PostScript driver instead of the HP ones.  I also changed the name of the hp folder under Library/Printers to "hide" HP's now-incompatible drivers etc.  I did not "upgrade" to AirPrint when prompted, hitting cancel instead.  (I don't want wireless printing.)  This has worked for me and my trusty LaserJet Pro, including duplex printing.  I arrived at this solution after following all the varied advice on the HP and Apple sites, deleting drivers, downloading them fresh and reinstalling, none of which fixed the problem.  So frustrating that these two companies couldn't spare us this aggravation and time sink, the very opposite of Plug 'N Play.
