Claim 5:
6. A method for controlling an image forming system, the method comprising:
forming a print image to be printed on a recording medium, based on a raster image and print setting information;
printing an image on the recording medium based on the formed print image;
reading the image printed on the recording medium to obtain a read image;
determining whether there is an error in the image printed on the recording medium, based on a result of comparison made between the obtained read image and the raster image; and
performing control, based on the determining, so that a sheet discharge destination for a recording medium on which an image which has been determined that there is an error therein is printed and a sheet discharge destination for a recording medium on which an image which has been determined that there is no error therein is printed are made different from each other,
wherein the determining determines whether, in the read image, there is an error in a region other than a predetermined region which has been set based on predetermined print setting information included in the print setting information in a case where there is a predetermined difference between the raster image and the read image and the predetermined difference is based on the print setting information.
