You’re always on the move, so maybe your printer should be as well. The HP DeskJet 3940 is an inkjet printer so lightweight and compact it’s actually portable. And to achieve that portability, HP hasn’t sacrificed any print quality. This machine is still capable of printing 16 pages per minute in black and white and 12 pages per minute in colour, with maximum print resolutions of 1200 x 1200 dpi and 1200 x 4800 dpi for black and white and colour, respectively.
