An image forming apparatus is configured to obtain information indicating the capacity of a toner container. In accordance with the obtained information, a gamma table for correcting the luminance value of a printing-target image is determined and the luminance value of the image is corrected by using the determined gamma table.

Image forming apparatus, image forming method, and storage medium

An image forming apparatus includes a plurality of light sources, a light source control unit that controls turning on and off of the plurality of light sources, a first detection unit that detects an accumulated amount of waste toner with respect to the total capacity of the first waste toner container, and a second detection unit that detects an accumulated amount of waste toner with respect to the total capacity of the second waste toner container. The light source control unit turns on one of the plurality of light sources, based on detection results of the first detection unit and the second detection unit.

Image forming apparatus and control method of image forming apparatus

A verification apparatus according to one embodiment of the present disclosure selects an image associated with a code of a reference image switching sheet as a reference image when the code of the reference image switching sheet is read. An instruction is provided to discharge the reference image switching sheet to a set sheet discharging destination.

Verification apparatus and information processing method for selecting an image associated with a reference image

A printing system includes an image formation apparatus, an information processing apparatus, and a terminal apparatus. The terminal apparatus includes a reception unit configured to receive conditions of capabilities required for an image formation apparatus to be registered on a virtual printer, and a first transmission unit configured to transmit the conditions received by the reception unit to the information processing apparatus. The image formation apparatus includes a second transmission unit configured to transmit, to the information processing apparatus, capability information indicating a capability of the image formation apparatus. The information processing apparatus includes a registration unit configured to register the image formation apparatus on the virtual printer in a case where the capability indicated in the capability information transmitted by the second transmission unit satisfies the conditions transmitted by the first transmission unit.

Printing system, information processing apparatus, control method therefor, and storage medium

An image forming system capable of reducing the processing load of a print server. An information processing apparatus generates execution data for causing an image forming process to be executed. The print server holds the execution data acquired from the apparatus. A plurality of printers execute the image forming process based on the execution data. Print settings are set based on capability information of the printers and are transmitted to the apparatus. The information processing apparatus generates the execution data based on the received print settings. History information indicating one of the plurality of printers, which is used for printing, is managed, and the print settings are set based on capability information of one of the printers, which is selected based on the history information.

Image forming system capable of reducing processing load of print server, server system, method of controlling image forming system, and storage medium

A system is operable to save a print job received from an information processing apparatus and transmit the print job to one printing device among a plurality of printing devices that are registered in advance, in response to a request from the one printing device. The system includes a server, that generates capability information for the plurality of printing devices based on capability information indicating a capability of each printing device of the plurality of printing devices, and updates the generated capability information in a case that the capability information indicating the capability of one of the plurality of printing devices changes. The information processing apparatus generates and displays a print setting screen based on the updated capability information obtained from the server.

System, server and method of controlling the system and method of controlling the server

A server system that causes one of a plurality of printers to print an image received from an information processing apparatus. A virtual printer determines whether or not a printer capable of performing printing to which both of a first print setting and a second print setting are applied is included in the plurality of printers. In a case where it is determined that a printer capable of performing printing to which the first and second print settings are applied is not included in the plurality of printers, information indicating that the first print setting and the second print setting conflicting with each other is stored as prohibited settings information. The print settings are controlled based on the prohibited settings information.
