A network device transmits, to a server, information of an event that has occurred in the network device, compares, with each of a first threshold and a second threshold greater than the first threshold, a metric that corresponds to a state of the network device pertaining to the event, and switches a method of communicating with the server based on the comparison. When the metric exceeds the first threshold while communicating with the server in a polling method with first communication intervals and is smaller than the second threshold, the method of communicating with the server switches to a polling method with second communication intervals that are shorter than the first communication intervals, and when the metric exceeds the second threshold while communicating with the server in the polling method with the second communication intervals, the method of communicating switches with the server to a push method.

When virtual printers are collectively registered with a plurality of print services through one operation, a virtual printer may be registered also with print services not utilized. In the present invention, by acquiring information regarding print services, provided by a plurality of print services, and information regarding virtual printers registered with the print services, it is determined, on a basis of the information regarding the virtual printers and a printer ID of the local printer, whether or not the local printer has been registered as a virtual printer with the print services. Information regarding the print service with which the local printer is determined not to have been registered is displayed, and when instructed by a user to register the local printer with the displayed print service as a virtual printer, the local printer is registered as the virtual printer with the instructed print service.

Printer registration apparatus, display apparatus, and method for printer registration

In the case of displaying, as a list, information pieces on virtual printers registered in multiple respective printing services, the user may become confused when choosing a printer if virtual printers that correspond to a printer are displayed as different printers, consequently reducing user convenience. The present invention relates to searching for virtual printers registered in multiple respective printing services and generating a printer list that displays, as a group, virtual printers corresponding to a printer among the virtual printers thus found, on the basis of printer identifiers of the virtual printers.

A content management apparatus as an embodiment of the present invention associates content information on content with group information on a user participation group in a posting management service that approves control for the content, and stores the associated information. The apparatus then acquires group information on the user participation group from the posting management service, upon receipt of a content control request. The apparatus determines whether or not the requested control is to be approved, based on the acquired group information and the group information stored in association with the content information on the content. This configuration allows the content management apparatus for managing the content to control access authorization according to setting of the group in the posting management service.

Content management apparatus and content management method

An image forming apparatus includes a printing unit connectable to a print server system with a print service providing print data. The image forming apparatus includes a reception unit that receives a URL from the print service in response to receipt of a print instruction, the URL indicating a location where the print data is stored and receives the print data based on the received URL, and a transmission unit that transmits the received print data to the printing unit. The transmission unit starts communication with the printing unit in response to receipt of partial print data, does not disconnect communication with the printing unit before receipt of a remainder of the print data finishes, and disconnects communication with the printing unit in response to completion of transmission of all of the print data.

Image forming apparatus, control method, and storage medium

The necessity of a printer object is determined based on data to be printed, and in a case where the data type is such that a conversion to a printer language is necessary, a printer object is dynamically generated. With this, a distributed printing system that does not use resource pointlessly and for which efficient scaling out is possible can be realized.

Information processing apparatus, distributed printing system, and method of controlling printing

When an index file includes reference information about a next index file, a printer continues to acquire the next index file until the index file is overwritten with reference information about a newly processed file.

Information processing system, print system, server apparatus, and method for controlling information processing system

An information processing device acquires status information of a printer, and adds a status name indicating the acquired status information to a printer name of the printer and updates a printer name in printer information corresponding to the printer managed by a print service device with the printer name to which the status name has been added. Also, the print service device manages printer information undated with the printer name to which the status name has been added, and generates a print setting screen, on which the printer name to which the status name has been added is to be displayed, based on the printer information managed by the print service device and transmits the generated print setting screen to a user device.

Relay server, relay server control method, and storage medium

A print relay system includes a confirmation unit configured to check, in response to reception of a print instruction from a user apparatus, whether print information associated with second printer information that corresponds to a user who operates the user apparatus, of the second printer information included in printer management information, has been received from the print service, or whether a print job has been generated based on the print information. The print relay system further includes a transmission unit configured to transmit, in response to the confirmation unit confirming that the print job has been generated based on the print information associated with the second printer information that corresponds to the user, information including location information of the print job via the user apparatus to the image forming apparatus that executes the generated print job.
