A server transmits, to clients, display data for displaying a plurality of input areas for pieces of identification information which identify apparatuses in which software is to be installed. The server receives the plurality of pieces of identification information input to the input areas. The server then issues, to the clients, license information for permitting installation of the software to the apparatuses corresponding to the pieces of received identification information. This makes it possible to efficiently issue license information of software.

Method and apparatus for preventing unauthorized use of software

A transfer unit and an image output control unit are provided in order to check and prevent any alteration or forgery of image file data in a memory card. The transfer unit transfers a digital signature of the image file data stored in the memory card, a secret key used for the digital signature or a public key paired to the secret key, together with the image file data and a property file, to an image control apparatus. The image output control unit controls an image output in accordance with the information transferred by the transfer unit.

Image processing system and method, memory card, and storage medium

To obtain proper output results regardless of the type of recording sheets and obtain the user's desired output results without having the user perform cumbersome operations, the user operates an operating section to select a sheet feeding stage, gives an instruction to start copying, and then a controller sectionof an image forming apparatus determines whether or not a 180&#xb0; rotation mode for rotating image data through 180&#xb0; is set and/or whether or not preprint sheets are used for recording. If the answer is negative, the image data are output based on normal settings. On the other hand, if the answer is affirmative, the image data are output after being rotated through 180&#xb0;.

Image forming apparatus and control method for rotating image data based on sheet type and orientation

An image forming apparatus that forms images of originals on sheets, includes a plurality of feeders for feeding sheets, a memory for storing sheet types in association with the plurality of feeders, and storing the priority between the sheet types, and a selector for selecting one of the plurality of feeders to be used for a sheet feeding operation in accordance with the sheet types and the priority stored in the memory.

Image forming apparatus having function of automatically selecting one of sheet feeders, method of controlling the image forming apparatus and storage medium

An image forming apparatus that forms images of originals on sheets, includes a plurality of feeders for feeding sheets, a memory for storing sheet types in association with the plurality of feeders, and storing the order of priority between the sheet types, and a selector for selecting one of the plurality of feeders to be used for a sheet feeding operation in accordance with the sheet types and the order of priority stored in the memory.

An image forming system selects any one of plural image forming modes including a first mode, wherein an image forming process is performed such that plural images are arranged on an identical face of a sheet. The system performs the image forming process based on the selected image forming mode and inhibits a working process for the sheets on which the images have been formed When printing is performed for a postcard or the like, the system shortens a printing time necessary to print an output result desired by a user, obviates a user's erroneous operation, and prevents creating an unpurposed output matter.
