<P>PROBLEM TO BE SOLVED: To prevent print quality from deteriorating by preventing a white line in a main scanning direction from appearing in a printed result even when a feed amount set in each printer does not coincide with an actually transmitted feed amount, due to mechanical errors. <P>SOLUTION: Image data is generated by arranging the same dot line data as dot line data at a bottom edge in a plurality of columns of dot line data composing the first pass data at a top edge of the second pass data (step S14), and the image data is transmitted to a printer (step S16). Each time the printer performs printing for one pass, the printer carries printing paper only by a feed amount that is smaller, by one dot, than the number of dots composing a printing element group in a sub-scanning direction of a print head and executes printing processing on the basis of the generated image data. <P>COPYRIGHT: (C)2009,JPO&INPIT |
