Ask HN: Why are there no open source 2d printers?
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.

The 620n and 635n EIO cards support Bonjour:

Awesome, thanks! I didn't realize that the newer EIO cards were so backward compatible.
