<P>PROBLEM TO BE SOLVED: To solve the following problem: processing for a 180-degree rotation is not correctly performed in automatic double-face printing because decision of an even page and an add page in actual printing is counterchanged when the number of pages for preview display is odd because the count of the page is put forward even at the page for preview because a common module (hereinafter called a Unidrv) of a driver simplified development kit does not decide whether the delivered page is a page for the actual printing or a page for the display of the print preview though performing the processing such that an image rotated by 180 degrees is sent to a printer when the number of the pages counted from a printing start is even in the Unidrv. <P>SOLUTION: The number of the pages drawn so as to perform the preview display is counted by a print processor. The Unidrv is made to process a dummy page as the preview page when the number of the preview pages is odd, drawing processing of the head page of the actual printing is controlled such that the head page becomes the odd page when the number of the pages is counted from the printing start, and the 180-degree rotation processing in the automatic double-face printing can be correctly performed. <P>COPYRIGHT: (C)2008,JPO&INPIT |
