Called Prepeat, this inkless and tonerless printer can write, erase, and then rewrite documents using a special thermal process along with plastic paper. Unfortunately, “each printer comes with a price tag of about $5,517 (500,000 yen), and the plastic sheets come in lots of 1,000 at the price of $3,300.” Video after the break.

Such a hefty price tag means that only large paper-users might consider PrePeat. Smaller offices and individual consumers will likely stick with their old-fashioned printer and paper combos for now.
