Xerox is developing a new printing technology which does not require ink of any kind. The new technology includes reusable paper which can be printed and erased dozens of times and has the potential to revolutionize printing. New details on this upcoming technology, which was first reported in September 2006, are now revealed.
This is one of the most impressive pieces of technology I have heard about for a while. If this is a success and paper can be re-used over and over, then that could really cut down on waste.
