Abstract
A print data processing apparatus process variable print data includes a cache unit, a determination unit, a determining unit, and a writing unit. The cache unit caches image data generated according to a drawing command included in the variable print data as cache data in a cache memory. The determination unit determines whether it is necessary to write the cache data in a secondary storage medium that is different from the cache memory. The determining unit determines cache data to be written in the secondary storage medium, in response to the determination unit determining that it is necessary to write the cache data in the secondary storage medium, based on a number of pages to be processed before each cache data cached in the cache memory is used next. The writing unit writes the cache data determined by the determining unit in the secondary storage medium.
