<P>PROBLEM TO BE SOLVED: To easily print a corrected page only by designating 'differential print' by the UI of a printer driver while it used to be necessary to remember a corrected page, and to designate print and displace the corrected page at the time of updating and printing a document in a conventional manner. <P>SOLUTION: When 'differential print' is designated by a user, PDL object data generated by a printer driver are stored each time. At the time of performing print the next time, the stored data are compared with the PDL object data generated by this time printer driver by page units, and only the page whose data contents are different is transmitted to a printer to realize a differential print function. <P>COPYRIGHT: (C)2004,JPO |
