Paper that erases itself: Coming soon?

All offices have to balance the need to cut paper use with employees’ reliance on paper documents. Here’s an innovation that might soon let you achieve that balance.
Xerox has developed a self-erasing paper the company hopes will someday be used for all those documents workers print, read once and never look at again.
Here’s how it works:
The paper contains a compound that changes color when exposed to a certain wavelength of light, but then gradually goes back to normal. The “printer” uses a light bar emitting that wavelength to write on the paper. The printed documents remain visible for 16-24 hours or can be erased immediately by exposing the paper to heat.
Sounds pretty cool, right? Don’t count on using it just yet, though. Xerox says the venture will remain a “research project” for some time, though laboratory research has proved it can be done.

We already have that in the form of thermal printing. Look back at any of the receipts you get when purchasing at Best Buy (and other retailers) and you’ll see that in no more than 60 days, the fine receipt in nothing but a blank piece of paper (or at least completely illegible)
