The print control apparatus comprises a plurality of page buffers provided in units each corresponding to a page having a minimal or relatively small paper sheet size. A necessary numbers of page buffers are acquired and then released by a draw task or a print task according to the page size to be printed so that printing can be carried out even on large size paper sheets with less total capacity of the page buffers and printing can be carried out on average at the highest speed of the printer engine on small size paper sheets even if there is a page containing a lot of drawing data during a continuous printing operation.
