Paper becomes digital

Xerox researchers have developed an experimental printing technology, which they call "erasable paper" that creates images to last only a day, and the paper can then be reused.

Though still in a preliminary state, this technology blurs the line between paper documents and digital displays, and could ultimately lead to a significant reduction in paper use.

The "erasable paper" technology is developed by Xerox Research Centre of Canada (XRCC), in collaboration with PARC (Palo Alto Research Center), a wholly-owned subsidiary of Xerox. The company has already filed for patents on the technology.

The company believes this technology will someday replace printed pages that are used for just a brief time before being discarded. According to estimates by Xerox, two out of every five pages are printed in the office for a single viewing that consist email, Web pages, and other reference materials.
