So I'm an "old HP printers" fan. And yet I'd never ever buy anything from HP.
FWIW I'm very happy with Brother. We've got several Brother laser printers and "laser printer + scanner" and we're very happy with these. Zero problem.
HP fell really low.
You just buy a bottle and pour it in the reservoir.
No chips, no updates. No firmware.
It does have the cleaning head issue that jams and says you only can do it 3 times which I suspect is based on number of pages printed and not actual health of head but not sure.
Edit: once I disabled ipv6 on the inkjet. It caused it to drop its IP connectivity completely, about 40 times an hour. Lol. Took hours on the phone with HP to discover that.
I guess that’s an “advance” in their ability to extract rent from 30 year old IP.
Here's Brother starting to be evil: https://news.ycombinator.com/item?id=31860131
