This new concept design takes the lead from old pencils and uses it as ink for your printer. With the Pencil Printer pencil stubs can be re-used and made into ink to be used to print documents. It works by separating the wood and lead inside the printer. You simply put a pencil into the hole on the top right of the printer, start the machine, and then you’ll see the device printing on paper using the pencil powder. Designer Hoyoung Lee also adopts eraser to erase off the printed paper so that you could use the paper again. WOW!
