The Japanese company Sanwa Newtec has developed an ecological printer that works without ink, toners, or paper . The PrePear RP-3100 uses a thermal head that “prints” in black and white on a PET plastic “paper” whose contents can be erased to be reused over and over again (up to 1,000 times per sheet). Its manufacturers assure that its use not only saves the cost of manufacturing sheets of paper but also avoids the emission of 5.7 kilograms of CO 2 for each “folio” reused .
The printer, on sale in Japan, currently costs $ 5,600, and each sheet is available at a price of $ 3.35. For now it only prints in A4 size, and the drivers are exclusively available for Windows.
