As a result of the determination, when the page to be processed is not composed only of reusable objects, the RIPed data is not used, but the page to be processed is subjected to RIP. Meanwhile, when the page to be processed is not composed only of reusable objects, whether a common page coincident with the page to be processed is registered in a common page table 507 is determined. When registered as a result of the determination, the RIPed data is reused, and when not registered, the RIPed data is not used, but the page to be processed is subjected to RIP. <P>COPYRIGHT: (C)2010,JPO&INPIT |
