Abstract
A printing apparatus in which a printhead and a print medium intermittently move relatively to each other, and the printhead performs printing on the print medium during the relative movement. The temperature of the printhead is detected, the detected temperature is compared with a predetermined threshold value, and start of new relative movement accompanied by printing is controlled in correspondence with the result of comparison. The threshold value is set in correspondence with information regarding the number of pixels for which the printhead can perform printing during one relative movement. By this arrangement, reduction of output speed can be suppressed as much as possible, and inconveniences due to temperature rise of the printhead can be prevented.
