Abstract
A technique for improving image quality by correcting a paper feed error in a printer is provided. First, a test pattern is printed using one representative feed amount that is to be used in printing. A correction value for paper feed is determined by the printing result of this test pattern. Correction values for the other feed amounts are predicted from the correction value for the representative feed amount.
