Related: I have a HP 4000 with duplex, which is an absolute unit (beast) of a small workgroup laser printer. It's 20+yrs old, still going strong and parts are easy to get.

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.

See about replacing the network card on the printer, or updating its firmware. Newer firmwares frequently support Bonjour, and have various security updates.

Replaceable NIC in printers are pretty great, especially when you can buy them for 1/10th of original cost on the used market.

They stopped manufacturing the HP LaserJet 4000 over 21 years ago, and the jetdirect EIO network card (J3111A) not long after that.

If there is a newer network card or firmware that supports this printer, I’d love to hear about it.
