    // This sample provides a number of forms that can be filled
    // and saved or printed right in the sample browser
    // using the 'save' or 'print' buttons in DsPdfViewer.
    // Note that if you print the filled form, everything is done
    // in the client browser, no data is sent to our demo server.
    // But if you click the 'save' button, the entered data along with
    // the original form are sent to the demo server. The server uses DsPdf
    // to insert the data into the PDF, and sends the filled PDF form
    // back to the client. The demo server neither stores nor analyzes
    // the data.
    // Note also that the viewer's 'download' button will only download
    // the original form without the data. Unlike the 'save' button, 'download'
    // does not access the server, it only gets the original PDF that was loaded
    // into the viewer.
