HP 4000 Printer Driver

Starting this morning my MacBook Pro w/OSX 10.15.7 gives me a message that ""hpPostProcessing.bundle" will damage your computer." It points to a piece of software in the Library that I believe is the printer driver. I've used the laser printer for a very long time and new drivers are no longer available for it from HP. Did OS X recently change in some way that would obsolete this printer?

MacBook Pro 15″, macOS 10.15

There's a clash between the latest security update and older versions of HP drivers.


This should clarify what you need to do:
