The DEMO 07 conference begins today in Desert Springs, CA. One of the new companies that launch at this event is Zink.

Zink wants to revolutionize printing with a new solution that does not need ink cartridges or ink ribbons. The key to the ZINK process is the ZINK paper.
Dye crystals are embedded in the ZINK paper and are activated by heat from a ZINK printer. The crystals then colorize and apparently produce high-quality, long-lasting, durable, and affordable images.

Zink says to target the mobile market to enable you to print photos on the go.

Going with a special paper is not a bad idea. You anyway have to buy special paper for printing already. To not have to worry about ink and cartridges anymore is a nice thought.
ZINK Imaging is the technology inventor and the manufacturer of the ZINK paper. The company will partner with device makers who license the technology to deliver Zink printers.
