Abstract

In the printing apparatus according to the present invention, the central processing section determines as to whether an empty area required for loading of image data is available in a swap page used as a swap area of a real page or not, and directly loads the image data on the swap page and compresses the image data when an empty area is available in a memory of the swap page. On the other hand, when an empty area is not available, the central processing section loads the image data in a real page via a virtual frame buffer and transfers the image data to the swap page for compression thereof.
