The print template gets its parameters from the dialogArguments variable. The dialogArguments is equal to the second parameter of the call to both showModalDialog() and showModelessDialog(). The Microsoft print template loader passes a few parameters as properties of a single object that is being passed to the HTML print template. The object is referenced in the print template as dialogArguments. Among its other properties, we use the __IE_PrintType to detect what the executable asked for. The executable determines its calls according to the user's requests through its Web page. When you click the Print with Prompt button, the executable sends a request to the Web page, setting __IE_PrintType to Prompt. The property __IE_PrintType may assume one of the following options: Prompt, Noprompt, and Preview. After checking the request, we call the proper function to handle it.
