<P>PROBLEM TO BE SOLVED: To provide a network system and a program capable of controlling a device without installation of a device driver in a client. <P>SOLUTION: Upon receiving an application execution request involving a device operation, a control server 3 generates device control information for device control, and saves the device control information. Then, the control server 3 generates first response data to the application execution request and sends it to a client terminal 31. Upon receiving the first response data, the client terminal 31 sends a device operation request to a device 4. Upon receiving the device operation request, the device 4 sends a device control information request to the control server 3 to receive the device control information from the control server 3. Then, the device 4 operates according to the device control information, and sends result of the operation as second response data to the client terminal 31, and the client terminal 31 receives the second response data. <P>COPYRIGHT: (C)2012,JPO&INPIT |
