We've seen plenty of printers in our time, but this one is most definitely to our taste. Korean designer Jeon Hwan Ju, probably a beans person, has created the Riti Printer, which uses coffee or tea dregs in place of ink. It's probably good only for sepia printouts, but it's the kind of green tech we like very much.
Coffee or tea dregs are placed into the cartridge, mixed with a little water. You then move the cartridge left and right in the slot to print. It's not the most efficient printer for your home business, but, whether it's Lipton or Lavazza, it produces aromatic printouts you can personalise.
