"If you spend much of your working life on the move, you'll probably carry a
notebook PC with you. So, how do you get prints from it? You could pop into
an Internet café and hope they have something compatible, or you can carry a
printer with you. HP's DeskJet 460wbt is designed for print-on-the-move,
offering high-quality output in a small, light (comparatively) box, with
battery power and easy connection through WiFi or Bluetooth."
