HP LaserJet 4
The HP LaserJet 4 was a brilliant printer. In the mid-90s, I remember being especially pleased when I printed a postscript desktop publishing file on my Amiga in the house to a 720 KB formatted floppy, took it into the office, and printed it on the LJ4.
I reckon there must still be some LaserJet 4s kicking about still in use somewhere as they seemed pretty bomb-proof.
