Zink (Zero + Ink) is a new start-up built around a new inkless printing technology. “Dye crystals” are contained in special paper, so that the printer doesn’t need to carry ink or a print head. Heating the paper/crystals reveals the colors. This technology could allow for printers to get very small, small enough to fit in cameras, phones, etc. Zink is already showing off a camera with built-in printer (seen here) and a stand-alone pocket printer. Both are reported to be available in late ’07. The website has more (tho not much more) detail.
