A printing press includes a printing unit, a plate making unit, and a control unit. The printing unit has a plate cylinder. The plate making unit is provided in the printing unit and performs plate making for a plate mounted on an outer surface of the plate cylinder. The plate making unit is supported to be movable between an operative position where it performs plate making while closing at least part of the printing unit, and a wait position where it opens at least part of the printing unit. The control unit selectively operates the printing press at a first speed at which normal printing is performed and a second speed lower than the first speed. The control unit serves to enable the printing press to operate at the first speed when the plate making unit is located at the operative position, and disable the printing press to operate at the first speed when the plate making unit is not located at the operative position.
