An output system includes a terminal apparatus, an output apparatus, and an information processing apparatus that are interconnected via a network. The output system includes a unit that registers an output request for output data received from the terminal apparatus that is operated by a registering user, a unit that displays information on the registering user that has designated an outputting user operating the output apparatus as a delegate user and receives a selection of the registering user from the outputting user, a unit that receives from the output apparatus an acquisition request for the output request of the selected registering user and provides the requested output request to the output apparatus, and a unit that receives a selection of the output request from the outputting user, acquires the output data of the selected output request, and outputs the acquired output data at the output apparatus.
