<P>PROBLEM TO BE SOLVED: To provide a network system and a program that enable control of 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, saves the device control information, and then generates and sends to the client terminal 31 first response data to the application execution request. Upon receiving the first response data, the client terminal 31 sends a device operation request to the 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 operates according to the device control information, and sends the result as second response data to the client terminal 31. The client terminal 31 receives the second response data. <P>COPYRIGHT: (C)2009,JPO&INPIT |
