Abstract
In a printing apparatus which prints using a printhead, a printing controller for feedback-controlling driving of a motor includes a control information generation unit which generates control information for a driving torque of the motor on the basis of a first driving pattern, a comparison unit which compares the control information and a threshold for determining an overload on driving of the motor, and a setting unit which sets a second driving pattern for changing a load on driving of the motor by the control information, instead of the first driving pattern, on the basis of the comparison result of the comparison unit. Control of the motor is switched in accordance with the load state.
