摘要： A printing device includes: a second blade; a first blade portion including a first blade and configured to cut print paper by moving from a standby position at which the first blade is away from the second blade, via an overlap start position at which the first blade starts overlapping the second blade on a side of the second blade in a first direction, to a cutting position; a first blade guide located in the first direction relative to the second blade and configured to guide movement of the first blade with the first blade between the first blade guide and the second blade when the first blade portion moves from the overlap start position to the cutting position; and a warping prevention portion configured to press the first blade in a second direction opposite to the first direction when the first blade portion moves from the overlap start position to the cutting position, to prevent the first blade from warping into a convex shape in the first direction or reduce such warping.
