Alright, this is not just concept. PrintBrush is a real product, wirelessly connected via Bluetooth, powered by rechargeable batteries and print on any flat surface even fabric. It uses some super accurate optical sensor to detect and can print a full size A4 or letter format silently. Expected to be sold in 2010 at $199. Video after the break. (평면 위라면 종이고 천이고 가리지 않고 PrintBrush를 잡고 그 위에서 손을 쓱쓱 움직여 주기만 하면 자동으로 그 위에 인쇄가 된다고)
