A data processing apparatus that received destination information showing a data transfer destination through a network provides a destination ID as identification information for the destination information, and stores the destination ID together with the destination information. The user specifies the provided destination ID and instructs execution of processing at the date processing apparatus. The data processing apparatus transfers data obtained by executing the processing to a transfer destination corresponding to the specified destination ID.

Data processing apparatus and data processing system

There is disclosed a network system in which the position, attribute, and status of a desired device on a network can visually comprehensibly be grasped. A server manages location information indicating information on the device position in a hierarchical manner and attribute information from the device. Each device holds a plurality of status information (icon information) in accordance with various statuses of the device. A client holds map information corresponding to each class of the location information, and overlaps and outputs (display output) device status information obtained by communication by a polling system with the device detected by search in the server, and map information corresponding to the location information of the device.

System for searching device on network

A processing apparatus that is capable of dynamically updating a database when a processing device set for use is newly added, thus providing a process performed by the newly added processing device. In the processing apparatus, among a plurality of processing devices, a processing device that is not in use is set for use, and a registration request is issued for registering process designating information corresponding to the processing device set for use. Based upon the issued registration request, the process designating information corresponding to the processing device set for use is registered in the database.

Processing apparatus, data processing method, program for implementing the method, and storage medium

A device communicatable through a network by using an address corresponding to a predetermined communication protocol and capable of entering a power-saving state, the device includes a storage unit configured to store an address being used by the device, and a determination unit configured to determine whether the address stored on the storage unit is usable if the power-saving state is released. If the address stored on the storage unit is usable, the device uses the address.

Power-saving control method for a network device

A device includes: a storage unit configured to store predetermined data; a converter configured to convert the predetermined data stored in the storage unit into data in a predetermined format; a first image processor configured to convert the data in the predetermined format into data in a printable format; a printer configured to print an image based on the data in the printable format; an image capturer configured to capture the image printed by the printer; a second image processor configured to analyze image data corresponding to the image captured by the image capturer; and a storage controller configured to control the storage unit to store the predetermined data included in the data in the predetermined format acquired through analysis by the second image processor.

Device, device control method, and program

The invention provides a network device control apparatus which can set an IP address to be inherently set by using a general program while an erroneous setup of the IP address by the general program is avoided. In the network device control apparatus according to the invention, data is received from a network by using a standard protocol, a special attribute value is detected in the standard protocol with respect to the data, and when a destination physical address of the data is the same as its own physical address, various parameters are set in accordance with the attribute value.

Location information of each device connected to a network is managed in a hierarchical structure to display the location of each device in a manner easy to be recognized by a user. The location information of each device connected to the network is managed in the hierarchical structure and layout bit maps are stored in each client. When a client issues a device search request, the hierarchical location of the device whose location search was requested can be identified, and the identified location of the device can be displayed in a way to be easily recognized. When the client displays the search result, it is unnecessary for a sever to transmit the layout bit map to the client.

If the layout bit map corresponding to the search result does not exists, the device can be displayed and registered through visual operations at a desired position. When the client displays the map information, it is unnecessary for a sever to transmit the map information to the client.

System for setting location information in a device on a network

A system capable of displaying locations of devices connected to a network so as to be easy to understand for a user with managing location information of the devices in a hierarchical structure and capable of displaying event information about jobs issued by the user on a display unit. The system manages the location information of the devices connected to the network in the hierarchical structure, makes a client unit store map information so as to specify a hierarchical location of a device requested to be searched for if the client unit issues a request of searching for the device, and enables a display unit of the client unit to display information indicating the specified device location and information about a job issued by the user, by which the user can easily and visually understand how the issued job has been processed.

System for searching for device on network

According to the present invention, a search condition can be moderated to easily understand a desired device without performing re-search, even if there is no device completely matching the search condition. An attribute of an object class is extracted out of the search condition designated by an operator to search a device meeting the attribute. A matching state of each attribute of the search condition first designated by the operator for a result obtained from the above search is visibly displayed.

Device search system

A printer module for giving notification of the status of the printer receives a request from a host to the effect that the host be registered as the destination of printer-status notification. The printer module responds by registering the host as a printer-status notification destination in a notification-destination registration table. The registered information includes registration retention time. A time-out module in the printer deletes registration, for which the retention time has expired, from the notification-destination registration table.

Printing apparatus, printing system and method of controlling same

An object of the invention is to automatize monitoring processing for displaying on a display unit a status of a print apparatus which is receiving a transferred print job. In order to achieve the object, after print data is transmitted, as a packet received from a printer ( ) is analyzed to control start or end of status monitoring of the printer ( ) by a CPU of a computer system ( ), the packet received from the printer ( ) is also analyzed to monitor a status of the printer ( ) and then display monitored contents on a monitor ( ).

Printer status monitoring method and storage medium using packets

A printing system where a network board which connects a printer with a network is installed in the printer, and a parameter setting program for setting communication parameters is downloaded to the printer from the network board. The printer receives the download parameter setting program, stores it into a memory, and links a key-input processing program for an operation panel of the printer with the download parameter setting program. Thereafter, as numerical values of communication parameters of the network board are set by using the operation panel, the set communication parameters are outputted to the network board. This enables the network board to perform communication with the network, by using the input communication parameters.
