Abstract
This invention is directed to provide a printing apparatus and a printing control method capable of more accurately obtaining a carriage position and executing more precise printing. The printing apparatus includes a scale, having slits at predetermined intervals, provided along the carriage scanning direction, and an encoder provided on a carriage to read the slits and measure the carriage position in the scanning direction as the carriage moves. In the printing apparatus, based on at least a time interval between the measurement time of a slit currently detected by the encoder and the measurement time of a slit immediately before the slit, a time up to at least one point between the currently detected slit and the next slit is predicted. Control is performed to cause a printhead mounted on the carriage to execute printing at the at least one predicted point between the continuous slits.
