BUT, it's compute bound with modern print jobs, and is missing modern protocols like Bonjour.
What if someone open sourced a legacy printer? I'd love to re-brain this printer.
I have a relatively modern LaserJet that does IPP (and Bonjour) over WiFi, but it doesn't do 5GHz WiFi, it doesn't do IPv6, so I have it plugged into a server over USB instead, and the server running CUPS exposes it on the network.
