PROBLEM TO BE SOLVED: To more quickly performing processing when an image is enlarged or reduced and is subsequently printed.SOLUTION: A printer determines whether each of pixel lines is a color line or a white line. At the time of performing enlargement/reduction processing, the printer generates new color lines with an increase in a number of pixels according to a magnification factor of 3 when the color lines are processing objects, referring to first and fourth lines in a development image, and generates white line information of a number of pixel lines subsequent to the increase according to the magnification factor of 3 without the increase in the number of pixels when the white line information is the processing object, referring to second and third lines in the development image. Further, the printer generates print data on the basis of enlargement processing results and executes print processing on a sheet. On account of this, at the time of performing the enlargement/reduction processing, the printer generates the white line information only indicating that the pixel lines subsequent to the enlargement/reduction processing are the white lines when the white lines are objects. Accordingly, the printer can reduce a processing load and efficiently perform processing. |
