Example embodiments of the present invention include a server for providing screen data to be shared among a plurality of information processing apparatuses. The server receives a first request for obtaining operation screen data from a first information processing apparatus, stores in a memory a communication identifier for identifying a communication between the server and the first information processing apparatus, and transmits to the first information processing apparatus first operation screen data for the first information processing apparatus that includes the communication identifier. In response to receiving a second request for obtaining operation screen data from a second information processing apparatus being a mobile terminal, the server transmits to the second information processing apparatus second operation screen data for the second information processing apparatus that is associated with the first operation screen data for display, based on a determination indicating that a communication identifier of the received second request matches the communication identifier being displayed.
