Green Printer Uses Coffee For Ink
There exists a seemingly endless list of inventions meant to replace the normal ink cartridges found in printers with eco friendly alternatives. The latest mad product is the RITI printer designed by Jeon Hwan Ju.
The RITI printer uses coffee or tea dregs as ink. The user places the dregs into the top-mounted ink case, and then has to then manually move the ink case left and right to print their image. A bonus of this is that it uses no electricity. The flip side, of course, is that bulk printing is nearly impossible. You need a good old fashioned laser printer for that.
