‘printbrush’ handheld printer with built-in camera

designed by swedish engineer alex breton for his company printdreams, the ‘printbrush’ is an 8.8-ounce
handheld colour printer, usable on almost any surface with a simple swipe of the device.

to function, ‘printbrush’ continually emits laser beams, while optical sensors measure the scattering
of the reflected light to determine the velocity and direction of motion of the device, pinpointing its position
relative to the printing surface. a controller matches the location coordinates to a pixel map of the document
or image, and runs a series of algorithms to predict which pixel to print next and to formulate the ink
combinations required to reproduce 16 million different shades.

because of the high sensitivity of the sensors, ‘printbrush’ can work on almost any material, including paper,
wood, and fabric. early prototypes of the device were demoed at various technology fairs as early as 2003,
but now, after replacing the LED-based sensors with lasers and adding colour technology, the company
predicts the public release of the device for late 2011 or early 2012.

printdreams plans to produce two models of handheld printer: the ‘paintbrush 4×6′, which features a built-in 5-megapixel camera
and prints photos and documents of up to 4×6-inches at 600dpi; and the ‘A4′, which features 1200 dpi full-colour
for full-size documents. the devices are expected to retail for 99 euros (139 USD) and 149 USD respectively.

it is estimated that global adoption of random movement printing technology (RMPT) like those used in ‘printbrush’
would represent an annual saving of 325,000 metric tons of raw materials and 291 terawatt/hours of electricity.
