For an image processing apparatus that can execute a plurality of functions, a common area that can be shared by the individual functions is provided in addition to the memory areas that are prepared for these functions. During the printing process, a check is performed to determine whether the common area is available for use as a print buffer. When the common area is not available, an area prepared in advance as a print buffer is employed to print image data in a single buffer system. When the common area is available, a print buffer for at least one page is obtained in therein, and a plurality of print buffers are alternately accessed to develop and to output image data (double buffer system).
