Patent ID: 7328969

Claim:
A computer readable medium having a printing support program stored thereon, the program comprising a print data generating means for generating print data allowing a printer to carry out four-sided borderless printing on the basis of an image obtained by enlarging a print target image, wherein the program includes instructions for causing the computer to execute: an image displaying process to display the print target image smaller than actual image data so that a difference between an area of a displayed image and an area of the image data, occurred when printing, is at least larger than a print error amount caused by the printer with respect to each of the four sides; an image editing process to reflect editing done within the displayed, smaller area of the print target image to its image data; a calculating process to calculate a reduction ratio corresponding to a fixed enlargement ratio obtained from the print data generating means; and an output process to output a reduced image data to the print data generating means.
