Abstract

In a service providing system, a client includes a transmitting unit configured to transmit specification information associated with specifications of the client to the management server, a receiving unit configured to receive registration completion information from a management server, a transmitting unit configured to transmit a request for service information to a service providing server, and a service prohibition unit configured to prevent receipt of the service information from the service providing server until the registration completion information is received after transmission of the specification information. The management server includes a receiving unit configured to receive the specification information, an information registration unit configured to register the received specification information while associating the specification information with the client, and a transmitting unit configured to transmit the registration completion information indicating completion of registration of the specification information to the client. The service providing server includes a receiving unit configured to receive the request for service information from the client, and an information generation unit configured to generate the service information based on the specification information, in response to receipt of the request for service information.

Description

technical field [0001] Some aspects of the present invention relate to a service providing system that provides a service from a server to a client. Background technique [0002] Recently, there has been proposed a service providing system that allows a client to execute a function that the client does not have by requesting function execution from a server connected to the client via a network. An example of such a system is disclosed, for example, in Japanese Patent Provisional Publication No. HEI9-238215 (hereinafter, referred to as JP HEI 9-238215A). In the system disclosed in JP HEI 9-238215A, a digital copying apparatus requests execution of an image processing function from a host computer. [0003] In the service providing system, if the function of the server is modified, such as adding a new function to the server, a message about the modified part of the functions is notified from the server to the client so that the client can allow the user to selectively regis...

Problems solved by technology

[0004] However, the above-mentioned service providing system has such a disadvantage that the server cannot provide services to the client in response to a change in the specification of the client (for example, adding a printing option to the client or changing a paper tray).

In addition, user operations for adjusting specification settings on the client side become a heavy burden on the user
