20090035045PRINTER - In a printer which prints on a roll paper transported toward a discharge port and cuts the roll paper, an exchangeable lower cover is attached to the printer. The exchangeable lower cover defines a lower edge of the discharge port. A change of height of the discharge port is allowed by exchanging the exchangeable lower cover for another one. Hereby, it is possible to change specifications between one for holding a printed slip and the other for allowing the printed slip to fall freely. In the former specification, a brush provided at a periphery of an upper edge of the discharge port is in contact with a lower cover. On the other hand, in the latter specification, the brush is in distant from another lower cover.02-05-2009
