Coffee-drinking computer users may soon have a new use for their old coffee grinds if a new eco-friendly printer hits the market.
Featured in the Greener Gadgets Design Competition, the RITI printer apparently uses coffee or tea dregs to create computer printouts.
To use the printer just insert a piece of paper, place used coffee or tea grinds into the ink case on the top of the printer, then move the ink case left and right to print the image — no electricity needed, Greener Gadgets reported.
Because it works manually the RITI printer is not ideal for large projects and can only print in black and white, but it will save on the cost of buying ink and electricity.
