Taking the meaning of a portable printer to the next level, Epson and design firm Industrial Facility have unveiled a new series of portable color printers called Colorio, and these printers run on batteries. The printer features a lid that doubles up as a paper tray, which is neat.

A hidden area behind the paper exit door reveals a plethora of memory card interfaces - for up to 19 types of cards. The printer is equipped with a 2" or 2.5" LCD that lets you preview images before printing.

IR printing from mobiles is also possible, and Bluetooth is available as an upgrade. The three models currently available in Japan are Epson Colorio E-300, E-500 and E-700. No word on its availability in other markets.
