Abstract
A printing apparatus according to the present invention comprises a carriage configured to mount a printhead and reciprocate, a driving unit configured to move the carriage, the driving unit including a motor as a driving source, a measurement unit configured to measure a velocity fluctuation of the carriage, a correction unit configured to correct driving of the motor by correction data to reduce a velocity fluctuation of the carriage arising from cogging of the motor, and a setting unit configured to set a parameter which defines a periodic fluctuation manner of the correction data. The setting unit determines a current preferable value of the parameter based on the velocity fluctuation measured by the measurement unit for a current set value of the parameter, and sets a next set value of the parameter from the determined preferable value.
