The extensions contains two functions, CreatePdfFromHtml and CreatePdfFromUrl. For the first just feed the function the html and it will return binary data.

For the second function, the full url can be given to the function. Remember that most internet pages are not meant to be printed, so the result won't be as fancy.

The component uses the iText .Net library.
