A printing system performs control to input sheet information regarding a single set of sheets consisting of a plurality of sheets including a sheet loaded in a sheet feeding unit of a printing apparatus. The printing system performs control to, based on the input sheet information, register the number of sheets corresponding to a single set in management information in which a stock of sheets is managed. The printing system also performs control to, based on consumption of a sheet by the printing apparatus, update information managed in the management information.

Printing system, method for controlling printing system, and storage medium

When a reading target object that includes a light emitting region is set as a reading target, the light emitting region is detected by a reading mechanism of a reading unit. The reading unit is caused to read the detected light emitting region, and in the reading, a read operation by the reading unit is controlled based on change of an amount of light received from the light emitting region.

Reading apparatus, control method and storage medium storing program thereof

A reading control apparatus is directed to improving convenience for a user when a reading device is caused to read a display surface of a terminal apparatus having the function of changing the size of an image to be displayed on a display device, and includes a reading unit configured to cause the reading device to read, as a reading target, the display surface, which is a surface including the display device of the terminal apparatus operating in either of a first state where an image in a first size is displayed on the display device, and a second state where the image in a second size smaller than the first size is displayed on the display device, thereby acquiring image data, and a notification unit configured to, in a case where the terminal apparatus placed on a document platen is not in the first state, execute a notification process.

Reading control apparatus, control method, and storage medium

It is determined based on processing to be performed on image data generated by reading by a first reading unit and a second reading unit, whether to separate, into image data of the first surface and image data of the second surface, image data that has been generated by reading by the first reading unit configured to read the first surface of a document, and the second reading unit configured to read the second surface of the document, and that includes the first surface and the second surface. When it is determined to separate the image data, the image data including the first surface and the second surface is separated into the image data of the first surface and the image data of the second surface.

Image reading apparatus and control method

A screen image displaying image-data items in list form is displayed over a predetermined time period. Then, the display color of an image-data item of the image-data items, the image-data item corresponding to predetermined classification information, is changed so that the image-data item can be differentiated from other image-data items. Consequently, a user can clearly identify the classification of the image-data items and easily find an image-data item satisfying a condition without performing a complicated operation.

Method for image-display

This invention relates an image printing apparatus capable of copying by executing enlargement/reduction (E/R) processing optimum to an instructed mode. According to the apparatus, a copy mode and an enlargement rate are input. The use priority order of each enlargement/reduction (E/R) unit of the apparatus is decided. The enlargement rate is distributed to each E/R unit in accordance with the copy mode, decided use priority order, and the E/R rate upper limit value of each E/R unit. An image is copied by causing each E/R unit to sequentially execute E/R processing in accordance with the distributed enlargement rate and the decided use priority order and causing a printing unit to print based on the image data that has undergone the E/R processing.

Image printing apparatus and method of controlling the same

A plurality of images stored in a storage medium are classified into image groups. The number of images stored in the storage medium is compared with a threshold value determined based on the number of classified image groups and the number of images included in each image group. An image group selection sheet or a print specification sheet is printed depending on a result of the comparison. Thus, it is possible to automatically determine an optimum type of sheet for use by a user to select images and print the determined type of sheet without printing a large number of sheets.

Image recording apparatus and method of control for printing group selection sheet when number of stored images in group exceeds threshold

This invention provides an apparatus and a method capable of improving the throughput, reducing the apparatus cost, and executing marginless copy with a natural impression. According to this invention, a multi-function printer executes marginless copy in the following. Marginless copy and a printing paper size are instructed. The position and size of an original placed on the original table of the scanner are detected. A reading area on the original table is decided on the basis of the instruction, detection result, and a predefined extra-printing size. Control is done to execute image reading while limiting the operation range of the sensor of the scanner so that the image original is read from the decided reading area.
