Abstract
A printer according to this invention simultaneously performs image data generation and output in units of bands constituting one page. It is inconvenient to finish image data generation before output of the image data. Each band having a necessary rendering time longer than an output time of one band is picked up in advance. It is determined whether the memory capacity used is smaller in pre-rendering the picked bands or in simply increasing the number of band memories, thereby determining an optimal rendering schedule.
