Printer With No Ink Nor Paper

This is different from a conventional printers. This adopts a thermal head to print on specially made plastic sheets(special heat sensitive plastic sheets). These plastic sheets are not merely water proof, but could be easily erased. Just have to put the sheet back through the printer and different documents can be written over. And these PrePeat manufacturers claim that the sheets can be used up to 1000 times.
The PrePeat printer itself costs $5500, and each sheet of the special plastic paper is $3.30
