(57) A printing apparatus to imprint images on the top surface and also on a forward side surface of a set of keycaps. A printing sheet with an overlying cushioning sheet is placed on the keycaps, and a first set of contact surfaces presses portions of the printing sheet against the top surfaces of the keycaps, after which a second set of contact surfaces presses other portions of the printing sheet against the forward side key cap surfaces. This arrangement accurately locates the images on the keycaps.
