Although technology has progressed to such a point where going paperless is a viable option, to be 100% paperless might be asking for too much. After all, ordinary printing using an inkjet paper sure places a toll on the environment, what with the amount of ink used as well as paper. Enter the PrePeat printer which doesn’t rely on paper or ink – all you need to do is feed it special heat sensitive plastic sheets, where it will rely on a precision thermal head to print out gray scale text and images. Once you’re done with the printout, just feed the sheets through the printer again, where a different temperature setting will erase whatever was printed on it before. Sounds good, but the PrePeat printer is not for everyone due to the prohibitively high entry cost of $5,500, while each sheet of special plastic paper will retail for $3.30.
