In a printing apparatus, a dot head moves along a movement path which is orthogonal to a conveyance direction of a passbook, one end side of the head movement path is a speed-up area, a halfway part is a constant speed printing area, and the other end side is a slow-down area. A thermal head is disposed in a direction orthogonal to a conveyance direction of a thermal sheet, and a width size in the orthogonal direction is not smaller than the printing area of the dot head.
