PrintDreams is a really cool idea for portable printing. You download the output to it using a Bluetooth link, then you swipe it rapidly and randomly over any surface. It senses where it is and lays down ink in the appropriate spots to paint a decent-looking output onto the surface. It will be interesting to see how this works — I've tried out half a dozen wee printers and they all roundly sucked.
The printer has the length of a normal ball-point pen while its width and height are more or less equivalent to the width of a modern mobile phone. The total volume is less than 300 c.c. and weights around 350 grams. This first version of PrintBrush was designed to fit into a shirt pocket.
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.
