PROBLEM TO BE SOLVED: To employ a multithread system in order to enhance efficiency of the print work of a color printer while simplifying the structure for mounting it on a firmware. SOLUTION: A multithread control means 6 controls generation of tasks to be multithreaded, i.e., analysis for each color 1-4 (7-10), task rotation from analysis for each color 1 to analysis for each color 2. The analysis for each color 1-4 (7-10) analyzes each task to be multithreaded, i.e., a print data distributed by a receiving memory distributing means 5 to generate each data page 1-4 (11-14). Upon ending data analysis by a given volume of block, the multithread control means 6 performs rotation to next analysis for each color.
