Toshiba printer erases and reprints on a single sheet

Toshiba has unveiled a printer that can print, erase and reprint on a single sheet of special paper up to 500 times.
The B-SX8R uses specially engineered paper similar to the thermal paper used in early fax machines, except it can be erased and is much more durable. The sheets are made of plastic and can be recycled at the end of their lives.
Toshiba’s process uses a special pigment in the paper that reacts to heat. If heated above 180 degrees centigrade the pigment turns black, creating an image on the sheet.
However, if the surface is heated to between 130 and 170 degrees the pigment reverts to white, allowing the image to be ‘erased’.
Special marker pens are also available, which can be erased from the paper using an optional cleaning machine.
Toshiba is touting reduced CO2 emissions created during the paper production process.
