<P>PROBLEM TO BE SOLVED: To recognize changed contents when printing a print draft in which its contents are changed. <P>SOLUTION: A print management system memorizes PDL print data (print data described by a page description language) of a draft printed in the past. When printing of the draft is instructed by inputting the PDL print data of the print object draft, the print management system determines existence of any change by comparing both data if the PDL print data for the same draft printed in the past are memorized (affirmative answer at 102), and inquires of a print instructor about whether or not its change is regular by informing of changed contents (114) if any change is existed (affirmative answer at 108). The system cancels printing if the change is falsified (118), and adds data for printing changed contents on a printing matter to the PDL print data (124 or 128), and also executes RIP processing for evolving the PDL print data to bit-mapped print data (132) after registering the PDL print data to a data storing section (126 or 130). <P>COPYRIGHT: (C)2005,JPO&NCIPI |
