We have hundreds of printers across multiple bldgs at my company, but very few are HP. Sounds like you're already found this Apple KB, which is no longer maintained, but last updated on 09/24/2018?
Each vendor will likely have a corresponding JKB re: macOS Catalina-compatibility and/or driver?
Here's HPs KP... https://support.hp.com/us-en/document/c06141321
Thank you for the replies.
We have found compatibility to be all over the place with HP printers right now. I was looking for an updated HP Driver package but it doesn't seem Apple does that anymore. Some HP printers were straight up uninstalled after a Catalina update! We were able to get them back but using the Generic Driver.
If these are network printers it's probably best to switch them to IPP Everywhere and forgetting about drivers in light of this inevitability: https://www.cups.org/blog/2018-06-06-demystifying-cups-development.html
HP has a utility called Easy Admin that you can use to download driver packages for most printers I believe. At least I know the newer printers are in there. This was discussed in this Jamf Nation post:
We have tried switching to IPP Printing, but we've found that not all printers support this, yet. For example, some EFI Fiery controllers do not present all printer options (paper decks/trays, finishers, etc) when connecting via IPP. So while Apple is deprecating drivers in a future release, until the printer vendors fully support IPP over LPD we have to stick with LPD.
Looks like it could be the package itself. I was using the HP Printer Drivers v5.1 for OS X found here: https://support.apple.com/kb/DL1888?locale=en_US
The jamf installer log shows:
Installation failed. The installer reported: installer: Package name is Hewlett-Packard Printer Software
installer: Certificate used to sign package is not trusted. Use -allowUntrusted to override.
I just created a Self Service policy to install HP LaserJet 600 M602 using the HP Printer Drivers v5.1 for OS X and it worked fine. Might take a little longer to install the HP Printer Drivers v5.1 for OS X.pkg but it works.
the easy admin drivers (hp easy essentials.pkg) i downloaded look to be the same as the 5.1, so i used the 5.1 instead. In pacifist.app looks like the the essentials are installing all the HP drivers just like the 5.1pkg. When i tested the essentials, the kernel extension popped up while the 5.1 install did not popup approval for kernel extension
tested it on macOS 10.15 Catalina 2012 macbook pro
