For those of you who take pleasure in a cup of joy with your morning paper, the RITI Coffee printer propose an inventive way to green your morning ritual. The RITI printer uses coffee or tea dregs. The user put in the coffee or tea dregs into the ink case located on the top of the printer, then insert a piece of paper in the center. Moving the ink case left and right will print your picture, and as you draw on the paper, dregs inscript on the paper just like ink.
