<P>PROBLEM TO BE SOLVED: To eliminate the necessity of an excess printing time when grayscale-printing color-printing data, for example. <P>SOLUTION: When a host computer 12 (1) receives a print mode of a print job including color page data, a print mode setting part 12-1 makes a print command specifying the print mode be included in the print job. When the print mode setting part 12-1 makes a prescribed monochrome print mode be included in the print job, a print data conversion part 12-2 converts the color page data included in the print job into monochrome page data. When a print processor 3000 receives the print job, a print speed recognition part 15 extracts the print command from the received print job, a print speed designation part 16 designates a print speed according to the extracted print command, and a print engine part 200 executes printing processing of the received print job at the designated print speed. <P>COPYRIGHT: (C)2008,JPO&INPIT |
