I've had a fairly decent one with a Canon small-office B&W laser. It needs to be reset every so often, and it doesn't seem to like my wife (though no printer ever does), but its apps and drivers are mostly business related, so while they are more than happy to help you buy supplies, they don't force the issue, and the printer doesn't care what brand of toner you shove in it. 99% of the time it's just sitting there quietly on its LAN address, ready to print something successfully.

She just got an HP multi-function from work, and dear god that thing is annoying. It kept claiming that its own demo ink was counterfeit. Also fairly mediocre color prints.
