Patent ID: 8395808

Claim:
A print controller that magnifies an image expressed by master image data by a predetermined magnification and causes the magnified image to be divisionally printed in plural sheets of printing paper, said print controller comprising: one or more processors; memory; a command output module that outputs a command, which instructs printing in a printing area of a greater size than a size of the printing paper actually used for printing, to a printing device, the greater size being greater than the size of the printing paper by a quantity of enlargement that is individually determined according to the printing device in four directions of right and left, and up and down; a magnification module that magnifies the image expressed by the master image data by the predetermined magnification; an area setting module that sets multiple areas adjacent to one another in the master image data magnified by said magnification module, where each of the multiple areas has identical dimensions with those of each sheet of printing paper; an enlargement-extraction module that enlarges in the magnified master image data each of the areas which are set by said area setting module, by dimensions that are equal to the quantity of enlargement that is individually determined according to the printing device in four directions of right and left, and up and down and sequentially extracts image data included in each enlarged area, wherein each enlarged area includes a greater portion of the magnified master image data than a corresponding one of the areas set by said area setting module before enlargement; and an output control module that outputs each of the extracted image data corresponding to the printing area of the greater size to the printing device.
