The paper tray is movable between at least two positions, has bent-in edges that hold print paper, and has a registration pin that fits in holes in the base to locate the paper tray accurately in each print position. The back edge of the paper tray is bent up to slide along the back edge of the mask and is held in engagement with the mask by a bent-up retainer at the back edge of the base. A movable slide preferably underlies the paper tray and has a bent-down back edge that is movable forward for removing paper from the tray, and the slide preferably guides on the registration pin.
