If the company Zink has its way, you'll be printing on your own personal pocket printer, and you'll be printing without ink. That's right, no ink. Zink has announced a printing system that uses no ink. How can it print without ink? It uses special paper.
"In Zink's system, images are created when a heated printer head comes into contact with a sheet of specialized paper. The paper--which is actually a polymer but feels like ordinary photo paper--contains three crystalline layers. The layers are clear until heated. When heated, the material de-crystallizes and changes colors."
The ZINK printer will be able to print color photos about 2 x 3 inches. The company’s first products are likely to be a $100 pocket printer, or a $200 printer/camera hybrid.
