jimboh2k sends word of a printer introduced by Japanese company Sanwa Newtec, called the PrePeat RP-3100 (a play on "repeat"). It prints on A4-sized sheets of PET plastic, and these sheets can be reused up to 1,000 times, the company says. The printer uses heat transfer technology rather than ink, and so has no consumables. There's a video of the printer in operation at the link. The PrePeat costs about $5,600 and a supply of 1,000 plastic sheets will set you back another $3,300. However, the company gives a use case in which a corporation saves $7,360 per year on consumables, as well as putting less CO2 into the atmosphere. So far the PrePeat is available only in Japan.
