I bought a wireless colour Brother laser printer in 2010. I basically don't touch it except when something needs printing. No cleaning, no maintenance. Still has the original toner cartridges, still works great and prints instantly. Works with basically any OS trivially; it even supports lpd, so it should theoretically work with anything as recent as Version 6 AT&T UNIX, but I don't know anyone with a UNIX system from 1975 so I haven't been able to test that theory.
