Zuta, the robot printer that walks all over your paper

Why have print heads moving when you can have the printer walk all over the paper? Two students of the Jerusalem College of Technology came up with this idea which they want to develop with the help of Kickstarter. 
Their invention is a combination of robot technology, miniaturisation and a compact print head.  Zuta´s advantage is that there are no limits in the output size, except for the cartridge´s capacity. Zuta is with its 10×10,5 cm and 300 grammes very portable.
The black and white version is for sale for 180US$, colour is the next phase the start up is working on.
