Abstract: This is to provide an image processing apparatus and others capable of ensuring security by shortening the connecting time of an external recording medium when a plurality of jobs including target data pieces encrypted with shared keys and the shared keys encrypted with a user's public key are executed. A job including a target data piece encrypted with a shared key and the shared key encrypted with a user's public key are received and stored in a job storage. To execute the plurality of jobs stored therein, the encrypted shared keys included in the respective jobs are decrypted with a secret key by the external recording medium. After completely obtaining all the plurality of decrypted shared keys, the target data pieces are decrypted with their matching decrypted shared keys, and then the jobs are executed.

Abstract: It is recognized that an attached USB memory is an unanalyzable USB memory. Then, disconnect setting is made. A USB connection process is performed. A PC is instructed through a connection line to establish USB connection. The PC recognizes that the attached device is a USB-connected MFP. The PC acquires data control information of the MFP. The MFP then transfers, through the connection line, the data control information output from the USB memory.

Abstract: An image forming system includes: an image forming apparatus; and a linking apparatus that is linked with the image forming apparatus. The linking apparatus is operable in any of a plurality of modes including a first mode of contacting the image forming apparatus and executing a specific operation and a second mode of not contacting the image forming apparatus for a purpose of executing the specific operation. The image forming apparatus includes a mode shift command unit that, when the image forming apparatus shifts to a power saving mode, notifies the linking apparatus of a shift command indicating that the linking apparatus should be shifted to the second mode. Moreover, the linking apparatus includes: an operation mode control unit that shifts the linking apparatus to the second mode based on the shift command; and an access control unit that, after the shift to the second mode, prohibits the contact with the image forming apparatus, which is performed for the purpose of executing the specific operation.

Abstract: An image processing apparatus reads out job ticket data indicating first conditions used for executing a job and a permission to change each of the first conditions and lack thereof. The image processing apparatus, then, reads out a functional conditions table indicating a first group made by grouping second conditions having a common concept and a second group made by grouping the first group having a common concept. Then, the image processing apparatus presents, as options for changing a first condition to which applying a change is prohibited, second conditions included in a first group to which a second condition that is the same as the first condition belongs. The image processing apparatus presents, as options for changing a first condition to which applying a change is allowed, second conditions included in a second group to which a second condition that is the same as the first condition belongs.

Abstract: An information processing apparatus has a first device driver and a second device driver installed thereon to use a first device and a second device, respectively. When the first device driver is activated, an operation setting screen to perform operation setting for the first device is displayed on a display portion. If a user changes the target device from the first device to the second device while performs operation setting via the operation setting screen, the second device driver for the second device takes over a value set using the first device driver and recorded in a memory.

Abstract: When a user activates a printer driver recorded in a memory of an information processing apparatus, a setting screen to configure operation setting for the printer driver's matching image forming apparatus is displayed on a display of the information processing apparatus, and in the setting screen, an instruction portion to give an instruction to show the documents stored in a memory area of the image forming apparatus is shown. And when the user gives an instruction by using the instruction portion, a request to show the documents is transmitted to the image forming apparatus. Receiving the request, the image forming apparatus returns to the information processing apparatus, reference information to select a document among those stored in the memory area. And then, a selection screen to select a document among those stored therein is displayed on the display, based on the reference information received from the image forming apparatus.

Abstract: A presentation system comprises a data management apparatus for storing document data for presentation therein, a display device for displaying a plurality of pages contained in the document data, and a terminal device capable of performing communication with the data management apparatus. The terminal device sends request data for requesting attachment of an electronic sticky note to the document data to the data management apparatus via network communication according to an input from a listening user of the presentation. The data management apparatus determines a sticky-note attachment object page out of the plurality of pages, to which the electronic sticky note is to be attached, on the basis of page specifying data included in the request data. Then, the data management apparatus generates a file in which the electronic sticky note is attached to the determined sticky-note attachment object page.

Abstract: If a job executed on the data to be processed is stopped due to interruption of a wireless communication with an image processing apparatus and a portable terminal, which happens to occur while the image processing apparatus is receiving the data to be processed, which is transmitted by the portable terminal, the image processing apparatus examines if the portable terminals connected before and after stop of the job execution are one and the same, and requests the portable terminal to retransmit the data to be processed. And then the image processing apparatus resumes executing the job on the data to be processed, which is retransmitted in response to the request.
