A network print system which aims at printing high-quality image data of a form is generated using a Web browser. In response to a request from a client to print or to display a document, a server merges an appropriate template with the variable data to produce print data or display data, as the case may be; however, based on whether certain authorization or restriction conditions are applicable to the request being processed, the server in an appropriate case inhibits generation of print data or display data, so that the print request or display request is not fulfilled.
