A printing system includes a web application server, a storage client apparatus, and a printing apparatus to save the storage capacity. The storage client provides stored bibliographic information data to a web application server and, when the storage client apparatus acquires print instruction from the web application server, the storage client apparatus provides data, to be stored in the storage client apparatus, to the web application server in response to a provision request from the web application server. The printing apparatus acquires and prints corresponding data after acquiring a print request from the web application server. The web application server manages information of the storage client apparatus and the printing apparatus, sends display data to a client apparatus operated by a user, and acts on storage, print, and query requests.
