'' 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.
