Abstract: It is analyzed on the basis of received print data whether the print data is print data generated via a process path formed from a combination of the first application and first printer driver, or print data generated via a process path formed from a combination of the second application and second printer driver. Settings associated with the process of print data are made for each process path. The process of the received print data is controlled on the basis of the analysis result and setting contents.

On the basis of the determined operation mode, identification information containing the identifier of at least one of a plurality of image forming units provided in the image forming apparatus is transmitted in response to the received information request.

Abstract: An image forming apparatus transmits a log notification request to a server before log transmission. The server responds to the image forming apparatus by appropriately performing scheduling of a log transmission time to disperse a load. The image forming apparatus transmits a log at a time designated by the server.

Abstract: A data processing apparatus capable of efficiently collecting information useful for network failure analysis. If image data transmission to a host computer has failed, a packet acquisition start instruction is given from a data transmission control unit to a packet acquisition control unit. Subsequently, image data is retransmitted to the host computer. After completion of the image data retransmission, a packet acquisition termination instruction is given to the packet acquisition control unit.

Abstract: An information processing device which can communicate with an image processing device on a network is characterized by comprising a search indication unit for issuing a search indication for searching the image processing device on the network, a first transmission unit for transmitting a request for changing a power saving state of the image processing device on the network to a normal state in response to the search indication issued by the search indication unit, a second transmission unit for transmitting a search request for searching the image processing device after the request was transmitted by the first transmission unit, and a designation unit for designating a transmission range of the request transmitted by the first transmission unit, and characterized in that the second transmission unit transmits the search request to the transmission range designated by the designation unit.

Abstract: An image forming apparatus decides, in response to an information request transmitted from an information processing apparatus, a priority image forming unit from a plurality of image forming units in accordance with the states of image forming units. The image forming apparatus transmits identification information containing an identifier of the decided image forming unit.

Abstract: An information processing apparatus comprises: a management unit adapted to manage plural network addresses; an allocation unit adapted to, according to a request from an apparatus newly connected to a network, allocate, from among the network addresses managed by the management unit, the network address not allocated to other apparatus; a storage unit adapted to store the network address of a search server of performing a search according to a search request for searching for a device on the network and of responding to the search request by a searched result; and a transmission unit adapted to transmit the network address allocated by the allocation unit and the network address stored in the storage unit to the apparatus.

Abstract: An apparatus determines, when receiving a packet transited via a network in a power saving mode, whether or not the packet is a packet according to a predetermined protocol. If the packet is determined to be the packet according to a predetermined protocol, the apparatus analyzes the data of a succeeding packet described in a data description language, and instructs the apparatus to return from the power saving mode to a normal power mode depending on an analysis result.

Abstract: An information processing device which can communicate with an image processing device on a network is characterized by comprising a search indication unit for issuing a search indication for searching the image processing device on the network, a first transmission unit for transmitting a request for changing a power saving state of the image processing device on the network to a normal state in response to the search indication issued by the search indication unit, a second transmission unit for transmitting a search request for searching the image processing device after the request was transmitted by the first transmission unit, and a designation unit for designating a transmission range of the request transmitted by the first transmission unit, and characterized in that the second transmission unit transmits the search request to the transmission range designated by the designation unit.

Abstract: An image forming apparatus capable of preventing unauthorized printing while reducing manager's work load. IP addresses of host computers for which printing should be permitted are registered beforehand in a print permission list. When a print job is received, whether the IP address of a host computer from which the print job has been transmitted is present in the list is determined. If the IP address is not present, the received print job is not printed but stored. Subsequently, when the print job is selected and a print instruction is given, printing is executed. If the print instruction has once been given to the stored print job, the IP address of the host computer is added to the list. Subsequently, printing is executed without any print instruction when a print job is transmitted.

Abstract: In a search server, a search request for searching for a device is received from a client PC, the device satisfying a search condition included in the received search request is searched for, and a searched result is transmitted to the client PC. Further, it is judged whether or not an apparatus at a transfer destination to which the search request is transferred has been registered in the search server. If it is judged that the apparatus at the transfer destination has been registered in the search server, the search request is transferred to the registered apparatus at the transfer destination based on the received search request.

Abstract: In a case where a device fails to obtain time information, information relating to a job is generated based on an elapsed time from start of the device, thereby specifying the job processing time later. Or, in a case where a device fails to obtain time information, the device does not perform printing based on the job, thus preventing the job processing time from being set to unknown.
