Maybe, it was a period of time to see bulky computers of a room’s size and we started a journey towards nano technology. With everything compact and more compact, the Pen Printer is finally another example of all things compact, portable, minimalist design and handy. Well, perhaps even more! Pen Printer is also an excellent idea of recycling your abandoned pens ink. Actually, it uses the ink left in the used ball pens as cartridge to print on regular A4 paper. It has a battery and a standard USB interface to connect to a computer. Quite at an early stage, this cool Pen Printer concept is worth of future consideration and research.VIA Yanko Design
