A mobile telecommunications device is provided which has a printhead with an array of nozzles for printing a media substrate, a capper assembly movable between a capped position covering the nozzles and an uncapped position spaced from the nozzles, a drive shaft for feeding the media past the printhead, and a print engine controller for operatively controlling the printhead. The capper assembly is held in the uncapped position by the media such that it moves to the capped position upon disengagement with the media. During use, the print engine controller senses the number of complete and partial rotations of the drive shaft and adjusts the operation of the printhead in response to variations in the angular velocity of the drive shaft.
