Printer ink is pretty expensive, it would be cool to have a printer that didn’t need a new ink cartridge every five minutes, one has been developed called Prepeat, although it is quite expensive.
The Prepeat printer doesn’t use any ink or toner cartridges, instead it uses a special thermal head and plastic sheets to print and erase documents, which means you can use the same paper again and again.
The Prepeat printer uses a special paper which is made from plastic and the paper can be used up to 1,000 times to erase and re-print documents, check out the video below to see how it works
Unfortunately the Prepeat printer is pretty expensive at $5,517, and the paper is also expensive at $3,300 for 1,000 sheets. Lets hope this technology becomes more affordable in the future.
