Circa 2004 corporate IT mandated us to replace our HP4000 "war tank" with a HP3700, and under average output (about 20k printouts/month) it gave us a lot of headaches. Due to this we still printed really important stuff on the HP4000 and left the 3700 for fancy colour printouts, until one day when the HP4000 required a major repair and IT refused to spend money on it. It was probably thrown out at the dumpster.
That and the fact that someone else pointed out: the toners are really expensive.
