Jin Woo Han has come up with a roller printer concept that does away with the need to mess around with various paper sizes or loading trays, since it is capable of taking in anything from A4 to A3-sized papers. In addition, you can print an image or document according to your preferred length since the Roller Printer comes with a built-in cutter that trims the paper at the desired length. With the liberty to do so, I suspect that most print-happy folks will probably run out of ink sooner than they think. This remains a concept at the moment, but it would definitely be a good looking addition to the office.
