A printer for label printing includes a cutter to cut a continuous label after printing at a position inside of the surface with respect to the outer case of the printer. A separation sensor is disposed between the cutter and the thermal head. A sheet detection sensor is disposed downstream of the cutter in the feeding direction. The sensors are mounted in two stages on a common circuit board. The circuit board is disposed vertically along the feeding direction of the continuous label within the region where a cover-open button to open an opening and closing cover of the printer is disposed.
