    I have a really old one that doesn’t do part pairing and is new enough to do color so it’s worth holding on to. The ink expiration, refill and status is still locked and it still can still brick specific ink cartridges if detects stuff like low ink or whatever. At least non-hp cartridges aren’t all-out blocked. I might have to steal all the information in the post so I can build my own whatever that is before hp sues everyone involved and purges it from the internet.

    Some day I hope I’ll find a way to refill the cartridges with ink and hack them to reset the ink levels.

      I have a rather old office laser from like 20 years ago and it is amazing. No DRM and I buy really cheap ink cartridges. The HP site does sell my cartridge still… For over $200.
