Abstract: A time limit for a printer to be restored to a printable state after an occurrence of a print error that prevents the printer from printing is variably set. If the printer is not in a printable state when an elapsed time since the print error occurred in the printer reaches the time limit being set or exceeds the time limit, a print start command is transmitted to another printer, and a job assignment is switched to the other printer.

Abstract: An image forming apparatus prints images of different document sizes on paper having a predetermined paper size. The image forming apparatus includes a computation processing part to compute a print position of the image with respect to the paper, based on the document size, the paper size and moving amount computation information that is input thereto, and a print processing part to arrange and print the image on the paper, based on the print position computed by the computation processing part.

Abstract: When a printing device is in a state in which a printing process of a print job including at least one print data and a series of process commands from a host apparatus cannot be executed, a printing processing unit transfers a printing right corresponding to the print job that is left unprinted to other printing device. When the printing device is in a state in which the printing process can be executed and if the printing right corresponding to the print job that is left unprinted is transferred to the printing device from the other printing device, the printing processing unit executes the printing process.

Abstract: A printing apparatus performs a printing process for a printing job including at least one print data and a series of process commands from a host apparatus. A session setup unit sets up a session with the host apparatus and other printing apparatus. A status obtaining unit obtains a status of the other printing apparatus that is in session with the printing apparatus. Upon performing the print process, a job synchronizing unit maintains a synchronization of the print job with the other printing apparatus that is in session with the printing apparatus.

Abstract: A first transmitting unit transmits print hold information to other printing apparatus connected on a downstream side in a data transmitting direction. A second transmitting unit transmits printing data from a host apparatus to the other printing apparatus. A third transmitting unit transmits page deletion information to the other printing apparatus every time a page is printed. When a printing condition cannot be satisfied, a fourth transmitting unit transmits print-disable information to the other printing apparatus, and releases a hold of the printing process in the other printing apparatus according to the print-disable information.

Abstract: An image forming apparatus is disclosed. The image forming apparatus includes a displaying unit which displays a predetermined number of menu items in plural menu items on a screen, an inputting unit which selects a menu item from the menu items displayed on the screen by the displaying unit, and a storing unit which registers the menu item selected by the input unit in a user custom menu table for each user having registration regions where a predetermined number of menu items are stored.

Abstract: An image forming apparatus which requests authentication for login processing based on user information when a user requests specific processing includes a communication interface for receiving data, a print mechanism for performing printing processing on data, a registration mechanism for registering a plurality of user information, a storage mechanism for storing an access control list and an administration mechanism. The administration mechanism administers login processing of a plurality of users based on hierarchy information of the registered users and registered contents of the access control list, and to administer permission of the operation processing requested by the user. When the user instructs specific processing of data which is a guest job having no authentication information, the processing of the data is carried out.

Abstract: A data processing apparatus includes a memory unit configured to store data received from an information processing apparatus, a receiving unit configured to receive operation requests, though respective interfaces, with respect to the data stored in the memory unit, an authenticating unit configured to authenticate a requester of an operation request, an operation performing unit configured to perform an operation according to an operation request received by the receiving unit only if the authentication unit successfully authenticates a requester of the operation request when the data on which the operation is performed requires authentication, and an operation prohibiting unit configured to prohibit the operation performing unit from performing a first operation corresponding to a first requester on given data until a second operation is completed if the authenticating unit successfully authenticates a second requester requesting the second operation to be performed on the given data.

Abstract: When it is determined that an image cannot be formed from an image data under an image formation condition, a display input controller accepts an input of a replaced image formation condition. An image formation unit forms an image from the image data under the replaced image formation condition. A storage processor stores the image data and the image formation condition in a storage unit when the image is formed by the image formation unit. When reforming an image from stored image data, the image formation unit forms the image under stored image formation condition.

Abstract: According a charging system of this invention, an AC required for charging of an electric double layer capacitor of a storage device in the body may be transmitted from a feeding device outside the body through power receiving and power transmitting coils. The electric double layer capacitor may be charged in a contactless mode, without incising the body of the artificial organ user, while the storage device remains embedded in the body. The electric double layer capacitor may be charged reliably by avoiding a shortage of charging since the charge status of the electric double layer capacitor of the storage device is known during a charging operation.
