HP Color LaserJet 3600n not printing macOS 12.1
I recently purchased this printer second hand. I plugged it into my MacBook Pro and set it up as I normally would in system preferences. Whenever I try to print, the little printer app shows up in my dock, the status proceeds as normal and eventually it vanishes from the list indicating the print has completed. But the printer never prints.
Is there any way to get this thing working? I've tried everything in this thread: https://discussions.apple.com/thread/252006315, but none of the drivers I've been able to find online will install in macOS 12.1 and the firmware files will not open at all.
Any help is appreciated! Thanks.
