Internet content, SMS, pictures and other information is downloaded to the PrintBrush from PDAs, mobile phones and laptop computers via a Bluetooth wireless link. Then, by following the RMPT principle the device is hand operated by sweeping it across any type of print media, no matter what its shape, size or thickness. The printout will then start to appear right behind the sweeps. The device takes into account all the parameters of the hand movement, including rotation and sudden changes of speed and acceleration. The resulting image on the printed media is very much like its digital counterpart.
