A printer has two separate movable blades, a stationary blade, and a movable blade drive mechanism for driving the movable blades against the stationary blade. Such mechanism may link and drive the movable blades to cut the roll paper against the stationary blade such that one movable blade leads and the other follows. The printer may further include a main frame with a roll paper compartment and a printing mechanism for printing on the roll paper, a cover frame movably connected to the main frame and having an openable cover for the roll paper compartment, a movable blade frame disposed to the main frame for supporting the movable blades with the blade tips in opposition, and a stationary blade frame disposed to the cover frame for supporting the stationary blade in a position substantially transverse to the paper transportation path during cutting.
