ABSTRACT:
A print head is operable to perform printing with respect to a medium. A motor is operable to move the print head. A guide unit is operable to guide the print head along a predetermined direction. A determination unit is operable to determine whether or not the print head performs a stick-slip operation. A motor control unit is operable to generate a command value for controlling the motor when moving the print head. The motor control unit generates a command value for moving the print head at a predetermined target speed on the basis of determination of the determination unit that the print head does not perform the stick-slip operation and generates a command value for moving the print head at a target speed faster than the predetermined target speed on the basis of determination of the determination unit that the print head performs the stick-slip operation.
