Mention portable printer and the idea of a device which fits into your pocket comfortably will probably never occur to you. Zink has done what looked like the impossible by offering a tiny printer that uses special paper for printing, doing away with the need for ink. This printer does small images that measures 2″ x 3″ in full color, and will most probably retail for $100 each. There is also talk about a printer/camera hybrid that retails for $200. You can read more about the special Zink paper in our piece yesterday. Availability of Zink products are still unknown.
