Who says printers only use paper to print documents? It’s time for you to meet the PrePeat Printer then. Different from conventional printers, PrePeat adopts a thermal head to print on specially-made plastic sheets. These plastic sheets are not merely water-proof, but could be easily erased, just feed the sheets through the printer again, and a different temperature will erase everything or just write over it. Also claimed by the manufacturer, such one sheet could be used up to 1,000 times so that you’ll reduce your expenses on paper for sure.
