Still using an HP LaserJet 1200 I bought in 1999. Uses the 75X toner cartridge, which is still in production. Costs about $50 for ~5000 sheets worth of printing (which is about 5 to 6 years). Has a USB port, so it's networked through an Apple Airport Express. 600dpi, and does envelopes just as well. The drivers are the old school LaserJet/JetDirect drivers, so they'll likely be supported until the heat death of the universe. Way back, I used to see these things in the field that have printed 15-20 times as many pages without even needing a replacement anything. I think 300-500K sheets is when they needed basic servicing. I think I paid $600 in 1999. Not cheap, but 17 years of foolproof dead reliable service and not even needing to install/configure drivers has made it worth every cent.
