Trusted Reviews looked at the HP LaserJet 1018 Personal Laser

This is a simple, bread-bin shaped printer, with a sloping top surface
and folding paper trays. The idea is that when it's not printing, you fold up the paper feed and output trays, leaving a machine with a footprint on the desk not much larger than a manila folder. There's no fixed input tray, but instead, when you fold down the front cover, you find guides for a paper stack of up to 150 sheets. Unusually for this design of machine, there's also a single-sheet, priority feed for an envelope or special media.
