Especially in offices and large corporations, every day are done thousands of "useless" printouts, as emails, drafts, internal memos, and so on. Documents that are mean to last less than one hour, but that must be printed to enhance productivity. But, using a new Japanese device it's possible to "delete" and "reprint" this papers, without using ink, toners or cartridges!

I am talking about the Sanwa Prepeat printer, it's a little bit pricey, about $6000, but can print on rewritable PET sheets. Sure, sheets are pricey too, $3 and are sold in 1000-sheets boxes, but if you consider that delete and rewrite can be done for free, for large corporations it can be convenient.

Jut take care to write on this expensive media using special felt tip markers and don't fold the sheets
