Trak is a concept mobile printer where you can place it on the back of your laptop display. This detachable printer uses USB connection as its power, ultra compact design which is very suitable for travelers or mobile workers. Too bad there is no technical detail on how we insert the paper, because I don’t see any paper tray here.

Not very far from reality. Applications abound…….
Just bring paper and because its only portable all you would have to do is insert one paper at a time.. Its not a printer its portable
