ABSTRACT:
A printer provided with a micro-electro-mechanical printhead for producing wallpaper, the printer comprising: a micro-electro-mechanical printhead extending at least the width of a media web; drive means to drive the media web past the printhead; at least one processor to receive and process a selected wallpaper pattern and to control printing of the wallpaper pattern, by the printhead, on the media web; the printhead including of a plurality of printhead tiles arranged along the length of the printhead; a fluid channel member adjacent the printhead; each printhead tile including a series of micro-electro-mechanical nozzle arrangements, each nozzle arrangement in fluid communication with the fluid channel member; and, each nozzle arrangement comprising: a nozzle chamber for holding fluid; a lever arm for forcing at least part of the fluid from the nozzle chamber; an actuator beam for distorting the lever arm; and, at least one electrode for receiving an electrical current that heats and expands the actuator beam.
