XEROX workcentre 3119
Mine's one of the first small relatively low priced laser-printers I saw on the market, the monochrome XEROX workcentre 3119, which cost about $US 130 in 2009.
That replaced an HP ink-jet, which was surplus to requirements at work, so the the boss gave it to me. I used it for several years, but go sick of it running out of black ink at inconvenient times. I never used colour.
I had a heck of a time getting a driver to use it with a Mac. XEROX hadn't yet got a driver for Mac on-line. The shop that sold it to me weren't very helpful. They put me on to the XEROX people in Bangkok, who suggested I pop in to Pantip Plaza, a small matter of 900 km (550 miles) away.
Eventually I went to the local Apple dealer. They were more helpful, locating and then e-mailing me a driver. It worked ok for printing, but when I updated to Snow Leopard I couldn't get the thing to scan. That was resolved when I updated to Mountain Lion, and a printer updated came through soon after.
Once I got on to paper that suited it, the workcentre has been ok for my needs. It seems a bit fussy about paper, jamming quite a bit with some types.
