Abstract: An inspection system inspects a grade of a print product based on comparison between a scanned image obtained by scanning a print product and a reference image, receives a first mode that does not switch a sheet discharge destination of the print product regardless of an inspection result of the print product or a second mode that switches the sheet discharge destination of the print product according to the inspection result of the print product is received through a screen, and controls the sheet discharge destination of the print product based on the received mode and the inspection result.

Abstract: In a case where an inspection level to be used in determining quality of an image of an inspected surface of a printed sheet is set based on a comparison between a captured image resulting from imaging the inspected surface and a reference image, a plurality of inspection regions varying in inspection level is set for the reference image. In a case where an overlap region is present in the plurality of inspection regions, an inspection level of the overlap region is identified based on a predetermined priority. Further, the identified inspection level of the overlap region is displayed.

Abstract: Printing is performed based on a print job received from an information processing apparatus, the information processing apparatus is notified of a jam based on occurrence of the jam, and a reprint job for performing reprinting that is generated based on the notification of the jam is received from the information processing apparatus. A scanned image obtained by scanning a printed print product is transmitted to an inspection apparatus, and information indicating that an inspection result obtained by the inspection apparatus inspecting a quality of the print product is “fail” is received. Based on the reception of the information indicating the inspection result “fail”, the information processing apparatus is notified of a jam, and a reprint job for performing reprinting that is generated based on the notification of the jam is received from the information processing apparatus.

Abstract: Provided are a printing control apparatus, a method of controlling a printing control apparatus, and a storage medium capable of simplifying a process of updating information on a paper sheet for a tray for which update of the information is restricted. In a case where update of information on a print medium stored in association with a tray that is provided in an image forming apparatus and holds a print medium is restricted, a user interface is presented which requests to select whether to update the information stored in association with the tray to received update information. Then, the information stored in association with the tray is updated depending on the selection made via the user interface.
