Abstract
A method of using a mobile device to determine movement, relative to the mobile device, of a print medium being printed on by the mobile device is disclosed. The mobile device includes a printer. The mobile device further includes a sensor in a media feed path of the printer and a processing means. A surface of the print medium bears coded data indicative of a plurality of locations on the surface. The method uses the sensor to sense the coded data at a plurality of locations on the surface. The sensed coded data is decoded in order to determine the locations, and the movement of the print medium relative to sensor is determined from the locations.
