We were all promised a paperless office in the future. That hasn’t happened. There are still reasons to print things. That means spending a fortune on printers, ink and paper. But a new solution may be on the horizon.

PrePeat is a printer that doesn’t use ink. And it uses special heat-activated rewritable paper. Done with a document? Just feed it back into the printer. It’s erased and reused. This is pretty cool. It’s also kind of expensive. The printer costs around $5,600. And a lot of specialized paper will run another $3,360. But we can still dream of a paperless future.
