Abstract: A control apparatus includes a storing unit, a determining unit, a first notification unit, a selection unit, and a second notification unit. The storing unit stores attribute information of sheets to be stored in sheet holding units. The determining unit determines whether attribute information of sheets to be used by a job corresponds to the stored sheet attribute information. The first notification unit notifies, in a case where the determining unit determines that the attribute information does not correspond, a user that the attribute information does not correspond to the sheet attribute information. The selection unit selects the stored sheet attribute information to change the attribute information of sheets to be used by the job. The second notification unit notifies, in accordance with selection of the sheet attribute information, the user that the attribute information of sheets to be used by the job corresponds to the stored sheet attribute information.

Abstract: A control apparatus includes storing, display, selection, receiving, determining, and control units. The storing unit stores attribute information about a sheet to be stored in each of a plurality of sheet holding units. The selection unit selects a job displayed by the display unit. The receiving unit receives an execution instruction for the selected job. The determining unit determines whether attribute information about a sheet to be used in the selected job corresponds to stored sheet attribute information. The control unit performs control in such a way as to prevent first attribute information, about a sheet to be used in a first job determined as being inconsistent, from being stored for a sheet holding unit in which second attribute information, about a sheet to be used in a second job selected at earlier timing by the selection unit than the first job, corresponds to the stored sheet attribute information.

Abstract: A control apparatus includes a display unit, a storing unit, a determining unit, and a control unit. The display unit displays a job. The storing unit stores attribute information about a sheet to be accommodated in a sheet holding unit. The determining unit determines whether attribute information about a sheet to be used in the job corresponds to attribute information about the sheet stored in the storing unit. The control unit controls the determining unit, wherein, after determination processing by the determining unit has been completed. the control unit controls the determining unit to further perform determination processing in response to a change of the attribute information about the sheet stored in the storing unit, or in response to a change of the attribute information about the sheet to be used in the job.

Abstract: A method is provided for appropriately controlling, if paper information of a paper to be used in printing is not registered, registration of the paper information and the printing process. An image forming apparatus which stores in a storage area, attribute information of a recording medium used in printing analyzes, before printing, print data, determines before printing the print data whether attribute information matching the acquired attribute information is stored in the storage area, and registers in the storage area the acquired attribute information which is not stored in the storage area.

Abstract: Attribute information representing the attributes of a printing medium is stored for each printing medium. Upon receiving a print job which designates the attributes of a printing medium, it is determined whether attribute information representing the attributes designated by the print job is stored. When it is determined that the attribute information is not stored, the attribute information representing the attributes designated by the print job is newly registered.

Abstract: A printing apparatus has a sheet holding unit having a detection unit for detecting a size of a sheet which is held and a storage unit configured to store sheet information including at least a size of a sheet as information representing a sheet. The apparatus sets first sheet information selected by a user in association with the sheet holding unit from a plurality of items of sheet information stored in the storage unit and notifies the user of a mismatch in a case where a size of a sheet that the first sheet information set in the setting indicates, and a size of a sheet detected by the detection unit are mismatched.

Abstract: Attribute information representing the attributes of a printing medium is stored for each printing medium. Upon receiving a print job which designates the attributes of a printing medium, it is determined whether attribute information representing the attributes designated by the print job is stored. When it is determined that the attribute information is not stored, the attribute information representing the attributes designated by the print job is newly registered.

Abstract: A sheet processing apparatus capable of creating fold sections suitable for an apparatus that performs saddle-stitch processing on fold sections. A sheet processing apparatus includes a printer engine configured to form an image on a recording sheet. The sheet processing apparatus sets a bookbinding lap which is a distance between a first sheet end and a second sheet end of the recording sheet assumed to have been folded in two. A finisher creates the fold section by forming a folding line on recording sheets according to a reference line which is shifted from the centerline of the recording sheet by the bookbinding lap.
