  • Patent number: 11040557
    Abstract: A cutting head-including printer includes at least one driving roller, a pair of side pinch rollers, a center pinch roller provided between the pair of side pinch rollers, and a roller moving mechanism that causes the center pinch roller to approach, or to be separated from, the at least one driving roller. The cutting head-including printer sets whether to perform cutting after printing or to perform the printing after the cutting. During the cutting performed after the printing, the cutting head-including printer separates the center pinch roller from the at least one driving roller. During the cutting performed before the printing, the cutting head-including printer locates the center pinch roller at a position where the center pinch roller holds a recording medium together with the at least one driving roller.
