There are tons of portable printers out in the market right now, but none compare to the
“Trak” concept. The Trak seems no wider than a standard laptop and can even be attached to one, as shown in the image. It’s ultra compact with a detachable printer head, this thing will ‘almost’ fit in your pocket. It is USB powered. The concept also seems to only support standard size paper. The Track also doesn’t have a paper feeder, so it might be a hassle printing multiple pages. The price you pay for mobility?
