Control device for controlling an image forming system having an image forming apparatus and a sheet stacking apparatus

A method for a control device to control a system having an image forming apparatus to form an image onto a sheet based on an image forming job, and a sheet stacking apparatus having a stacking tray on which the sheet is to be stacked, the method comprising:

• storing, in a first storage, stacking state information indicating a state of sheets stacked and/or to be stacked on the stacking tray;
• controlling to generate a system configuration image that visualizes a configuration of the system, to generate a sheet bundle image that visualizes a sheet bundle stacked on the stacking tray, and to display a screen in which the sheet bundle image is combined at a position of the stacking tray in the system configuration image,
• wherein controlling includes controlling to display the sheet bundle image such that sheets of a processed job, sheets of a being-processed job, and sheets of a processing waiting job are distinguished from each other,
• wherein the processed job is a job for which processing is finished,
• wherein the being-processed job is a job for which the processing is being executed, and
• wherein the processing waiting job is a job for which the processing waits;
• and
• storing, in a second storage, a list of job attributes representing any one of the processed jobs, the being-processed job, and the processing waiting job in an order of discharge of the sheet having the image formed thereon from the image forming apparatus,
• wherein controlling includes controlling to display the sheet bundle image in an order on the list of job attributes.

A non-transitory computer-readable storage medium storing a program to cause a control device to perform a method for a control device to control a system having an image forming apparatus to form an image onto a sheet based on an image forming job, and a sheet stacking apparatus having a stacking tray on which the sheet is to be stacked, the method comprising:

• storing, in a first storage, stacking state information indicating a state of sheets stacked and/or to be stacked on the stacking tray;
• controlling to generate a system configuration image that visualizes a configuration of the system, to generate a sheet bundle image that visualizes a sheet bundle stacked on the stacking tray, and to display a screen in which the sheet bundle image is combined at a position of the stacking tray in the system configuration image,
• wherein controlling includes controlling to display the sheet bundle image such that sheets of a processed job, sheets of a being-processed job, and sheets of a processing waiting job are distinguished from each other,
• wherein the processed job is a job for which processing is finished,
• wherein the being-processed job is a job for which the processing is being executed, and
• wherein the processing waiting job is a job for which the processing waits;
• and
• storing, in a second storage, a list of job attributes representing any one of the processed jobs, the being-processed job, and the processing waiting job in an order of discharge of the sheet having the image formed thereon from the image forming apparatus,
• wherein controlling includes controlling to display the sheet bundle image in an order on the list of job attributes.
