Just tried to print to my HP Color LaserJet Pro MFP M277 dw and got a message pop up on my iMac

Hey there! I’ve seen this after the update as well, I think HP drivers are out of date and need to be updated to work. Here’s what worked:

First, if updating the software manually doesn’t work:

Open Finder, on the top menu hit Go > Computer > Macintosh HD (Usually) > Library > Printers.

Save (If you need to, and Delete the HP folder from there, (You’ll notice when clicking “Show in Finder” when you get the errors, these are where the files are, in this case old, outdated drivers and files).

Once deleted, open System Preferences > Printers and Scanners.

Right click (or Control click) select “Reset Printing System”, (This will delete any existing Printers and Scanners).

Once done:

If USB Printer, dis connect/re connect, you may see the option to “Install” the new HP software.

If a wireless “AirPrinter”, just hit the “+” sign to re-add the printer and select “Add”.

Do a test print to make sure it’s working again!

This is Gatekeeper, Mac’s security doing its job, most likely if you’re getting that error message, it’s a good thing to remove the older software.

Hope it all goes well!
