Abstract
A printer driver conserves recording paper by removing blank space formed at the top and bottom of each page when printing. The printer driver acquires the coordinates of the top and bottom of the part of the print image, and calculates the page length required to print the middle area between the top and bottom blank space areas based on these coordinates. The print data for printing this middle area is then extracted and printed. When printing is completed, the recording paper is conveyed only the difference between the page length and the transportation distance of the recording paper to set the print head to a position separated only the page length from the printing start position of the area print data, that is, to a position touching the middle area. As a result, blank space between the middle areas of consecutively printed pages is eliminated.
