Xerox is working on a new form of printer/copier paper that can be reused. The printed information on the document would disappear within 16 hours:
The documents can be reused more quickly by simply placing them in the copier paper tray. The researchers said that individual pieces of paper had been printed on up to 50 times, and the only current limit in the process appears to be paper life.
“People really like paper,” said Eric J. Shrader, a computer scientist who is area manager for printing systems at the Hardware Systems Laboratory of the research center, which is known as PARC. “They like the way it feels.”
The project is still very much in a laboratory phase, he said. The researchers are still trying to refine the process, both to increase contrast and to extend control over the lifespan of the print process.
