Abstract:
1. An image forming system comprising: a printer controller that applies a rasterization processing to print data in regard to a print job so as to generate rasterized image data in regard to the print job, the printer controller being provided with a first storage section to store data being necessary for reapplying the rasterization processing to the print data in regard to the print job, therein and an image forming apparatus that has no function for re-rasterizing the rasterized image data from the print data, but receives job data including the rasterized image data generated by the printer controller, so as to perform an image forming operation based on the rasterized image data included in the job data received from the printer controller, the image forming apparatus being provided with a second storage section, a display operating section and a control section, wherein, in the image forming apparatus, the control section makes the second storage section store the job data in regard to the print job received from the printer controller therein, and accepts editing operations including an operation for changing a page order of pages included in the print job, inputted through the display operating section, so as to determine whether or not it is necessary to regenerate re-rasterized image data by reapplying the rasterization processing to the print data, based on contents of the editing operations inputted through the display operating section, and wherein, when determining that it is necessary to regenerate the re-rasterized image data, the control section of the image forming apparatus transmits only a predetermined regeneration request including page information for indicating a revised page order, changed from the page order of the pages included in the print job, to the printer controller, without transmitting the rasterized image data, which included in the print job received from the printer controller and stored in the second storage section, and wherein, in response to receiving the predetermined regeneration request, the printer controller is adapted to reapply the rasterization processing to the print data using the data stored in advance in the first storage section, so as to regenerate the re-rasterized image data corresponding to the page information, and then, transmits the re-rasterized image data to the image forming apparatus, and wherein, in response to receiving the re-rasterized image data regenerated in response to the predetermined regeneration request, from the printer controller, the image forming apparatus is adapted to perform the image forming operation in regard to the print job, based on the re-rasterized image data.
