摘要:
A technique for distributed printing that ensures favorable operability within a sufficiently short time. The procedure first generates intermediate print data and executes the parallel rendering process by time sharing to sequentially convert page data on the first page of the intermediate print data into data adequate for the printers. Transmission of final print data converted for the first printer is carried out in parallel with the rendering process for the second printer. In a similar manner, transmission of converted final print data to the second printer and third printers is carried out in parallel with the rendering process for the next printer. The parallel rendering process sequentially converts page data on the second page of the intermediate print data into data adequate for the printers. Subsequently, the parallel rendering process sequentially converts page data on the third page of the intermediate print data into data adequate for the printers.
摘要:
A technique for carrying out distributed printing from a general-purpose application program. An application program generates print data and issues a print command. A virtual printer driver receives the print command and returns performance information with regard to performances of a virtual printer to the application program. The application program converts print data into data suitable for the virtual printer based on the performance information and transmits the converted print data to the virtual printer driver. The virtual printer driver stores the input print data in the form of an intermediate print file into an HDD. A distributed printing utility reads the intermediate print file, allocates intermediate print data in the intermediate print file to respective printers according to a distributed form set in a dialog box, and outputs the print data in a distributive manner to real printer drivers provided for the respective printers based on the allocation.

An information collecting device includes: a network interface unit which receives information on consumables from a plurality of devices connected through a network; a database access unit which accesses a database storing the information on consumables of each of the devices; and a control unit which controls the network interface unit and the database access unit. The information on consumables contains a device ID assigned to each of the devices and the consumption number of consumables as the number of consumables consumed by each of the devices. From the database, the database access unit acquires a value of a device ID field used to store the device ID, a value of a previous quantity field used to store the consumption number of consumables received at previous time, and a value of a total number field used to store the total number of consumables consumed by each of the devices.

A database access server that performs processing for making access to a database is provided. The database access server includes: a database access processing unit that performs processing for making access corresponding to a client access request, which indicates a request for making indirect access from a client to the database, to the database upon receiving the client access request, the database access processing unit performing the access processing by issuing a first database access request to the database and then issuing a second database access request to the database after the reception of a response to the first database access request; and a database access time measuring unit that measures access elapsed time from a point in time of the reception of the client access request, which is defined as access start time, to a predetermined processing point in time that is somewhere between the access start time and the issuance of the second database access request, wherein, if it is detected that the length of the access elapsed time measured by the database access time measuring unit is greater than, or is at least equal to, that of reference time, the database access processing unit cancels the execution of the second database access request.
摘要:
An ID issuing system that issues an ID in response to a request from a client includes: a plurality of ID issuing servers that execute issuance of the ID; and a history management device that manages the ID, which is issued by each of the plurality of ID issuing servers, by a history table. Either an issued state or a reserved state, which is a reserved but non-issued state, is registered as a status of an issuance history of the ID in the history table. Each of the plurality of ID issuing servers includes: a unit that registers an issuance history, in which the status is a reserved state, as an issuance history of an issue-wanted ID in the history table through the history management device before issuing the issue-wanted ID to the client in response to a request of the issue-wanted ID from the client; a unit that checks whether or not another issuance history different from the issuance history of the registered issue-wanted ID, which corresponds to the same ID as the issue-wanted ID, exists among issuance histories registered in the history table through the history management device regardless of the status; a unit that issues the issue-wanted ID and changes the status of the issuance history of the issue-wanted ID to an issued state through the history management device when another issuance history corresponding to the same ID as the issue-wanted ID does not exist; and a unit that stops issuing the issue-wanted ID when another issuance history corresponding to the same ID as the issue-wanted ID exists.
