I bought a laser printer by Brother a couple years ago and never had any problems with 'fake' toners, and it also runs perfectly using CUPS on Linux. I suppose people don't research refill options ahead of buying a printer? This ongoing maintenance cost would be the first thing I'd look into. My initial question wasn't meant to be a rhetorical one. I was genuinely curious if there is any upside/reason why one should buy HP (print quality or whatever.)
