The new Zuta Pocket Printer is about 4 inches wide and long and 3 inches high, and weighs about 12 ounces. It can connect wirelessly to smartphones, tablets, laptops and PCs via Wi-Fi, and is supported by Android, iOS, OS X and Windows.
To print, a person switches on the device, aligns it with the corner of a sheet of paper and sends the document to it. The printer's "omni-wheels" help it turn and move in any direction on a surface. Laser sensors help control the movement, speed and location of the device. It's a convenient and easy to use device which can be used anywhere.
