Can't install printer driver on macOS Catalina

[waldgeist]

I'm scratching my head around this for hours now. I'm trying to install the HP printer drivers for my Office Jet Pro 8600 Plus on a fresh MacBook Pro 16 with macOS Catalina, using the latest drivers from the HP homepage.

The driver install runs through the Easy Scan installation (although it always claims it hasn't been installed yet), but won't install the actual printer drivers. One the Easy Scan installation is finished, I can press a button to install the drivers, but I only get an error message (device software cannot be configured).

If I install the AirPrint drivers instead (using system preferences), the buttons change and the HP installer asks me to switch to the HP drivers instead. If I press that button, the same error shows up.

With the AirPrint drivers, I can use the printer, but not the scanner. It just won't show up in HP EasyScan. This is all pretty frustrating.

Did anyone manage to install the latest printer drivers on macOS Catalina? And if so, how? I'm clueless now.

The OfficeJet Pro 8600 is not technically supported in macOS Catalina.  And HP Easy Scan will require the HP Scanner driver to support that device which is in the full driver install. In another post I linked to the full driver install.  It seems to work just fine in Catalina but you would be using at your own risk.

Here is the other post with the link.
