る制御部とを設けてなるプリンタ。[Scope of Utility Model Registration Claim] In a serial printer that prints by moving the print heads arranged in a vertical line in the horizontal direction, the printing range (movement of the carriage) within the movement range of the carriage with the print head fixed first and second detection sections are provided on both sides outside of the amount The carriage is further moved in the same direction by a predetermined amount from the time when is detected to change the direction, and printing is performed from the time when the carriage is moved by a predetermined amount a from the detection by the first detection unit due to the movement due to the direction change. When printing is started, printing is completed, and the passage of the carriage is detected by the second detection section, Z-(a+X)=b is calculated, and the printer further moves a predetermined amount in the same direction after the detection by the second detection section. a control unit that controls the printer to repeatedly perform printing in the opposite direction from the time when the printer moves by the calculated amount of movement b from the time of detection by the second detection unit by the movement caused by the change in direction; A printer provided.
