Abstract:
A printing system, comprising:a memory device that stores image data; a first developer that develops print data into first image data having a first resolution in two crosswise directions, the first image data being stored in the memory device; a rearranger that breaks the first image data stored in the memory device into blocks of N consecutive lines, N being not smaller than two, and retrieves therefrom the first image data in blocks of N consecutive lines to rearrange N lines of retrieved image data into one line of image data according to a predetermined rearrangement scheme; a printing device that prints at a second resolution lower than the first resolution; a first printing controller that controls the printing device to execute printing based on the image data rearranged by the rearranger; a second developer that develops print data into second image data having the second resolution in two crosswise directions, the second image data being stored in the memory device; a second printing controller that controls the printing device to execute printing based on the second image data stored in the memory device; and a switching device that switches between the first developer and the second developer prior to development of print data.
