PROBLEM TO BE SOLVED: To provide a technique capable of efficiently supplying the rasterize data of plural continuous printing jobs to a print outputting device. SOLUTION: A print controller 20 successively generates rasterize data related with plural jobs, and software compresses and stores the data in a system disk 4. At the time of outputting the rasterize data to a print outputting device 30, the data are temporarily expanded and restored by a first compressed data restoring part 8, and then hardware compressed so as to be highly densely compressed by a second compressed data generating part 10, and transferred to a page disk 15 as a cache disk, and outputted to the print outputting device 30. The rasterize data stored in the system disk 4 are software compressed so that the transferring efficiency of the data from the system disk 4 to the page disk 15 can be improved.
