Many years ago, I spotted an HP Color LaserJet Pro m254dw online at Costco and bought it. It's been a fantastic printer. The toner never dries out, "empty cartridges" don't prevent it from printing. It is modern enough that I can use AirPrint to print to it, but old-school enough that it has an ethernet port. The supplies status page basically says "Just because it's at 0% doesn't mean you can't print, but maybe buy a new toner cartridge and replace it when the output gets bad." It didn't require any special drivers, there's no need to link an HP account, and it has a usable web-based management interface.
So far I have the following complaints about the printer:
* After some large amount of uptime (3mo? 6mo? I'm not sure) it won't respond to print requests. Rebooting it fixes the issue.
* Toner cartridges are expensive. I priced out something like $450CAD for a set of the three colour cartridges. I'm still on the starter cartridges and, even though they're "empty", the output quality is fine.
* The word "Color" in the product name is not properly localized to the Canadian market.
Obviously I'm grasping at straws as far as complaints go!
Honestly, this thing feels like I found a unicorn. I've been looking for a similar printer for my parents, but I haven't found anything from HP that ticks all of the boxes. The next one for them will likely be a Brother.
