A network system has a printer with an internal web browser connected to a web server. The printer has a request unit that sends an HTTP request with printer status information embedded in the URL to the server, a data acquisition unit that gets HTML data from the server, and a print unit that executes a printing process based on the supplied HTML data. The server includes a request receiving unit that receives HTTP requests from the printer, a data transmission unit that sends HTML data to the client, and a status management unit that manages the printer status based on the status information embedded in the URL of the HTTP request.
