Disclosed is an image forming system, in which the printer controller is capable of performing the re-RIP (Regeneration Raster Image Processing) in conformity with the revised page order accepted from the image forming apparatus. When determining that the re-RIP is necessary, the image forming apparatus transmits a regeneration request including revised page order information, changed from the original page order, to the printer controller.
