Abstract: A control device, to control a system having an image forming apparatus to form an image on a sheet based on an image forming job and a sheet discharge apparatus having stacking trays for the sheet, includes a storage storing stacking state information for each stacking tray, a generator, a display controller, and an input portion. The generator generates a system configuration image, and a sheet bundle image representing a sheet bundle stacked on each stacking tray based on the stored stacking state information. The display controller displays a screen in which the sheet bundle image is combined at a position of each stacking tray in the system configuration image. The input portion inputs designation of an image forming job corresponding to sheets to be taken out. The display controller displays an order of taking out the sheets corresponding to the image forming job designated through the input portion.

Abstract: To prevent a printing apparatus from performing unnecessary processes, there is provided an image processing apparatus which is communicable with the printing apparatus and comprises: a determining unit configured to determine whether or not authentication information of the printing apparatus has been set in a print job; and a controlling unit configured to control to not transmit the print job to the printing apparatus in a case where it is determined by the determining unit that the authentication information has not been set in the print job, and control to transmit the print job to the printing apparatus in a case where it is determined by the determining unit that the authentication information has been set in the print job.
