    HTML2PDF(HTMLTEST, "test.pdf", open=True)

For the conversion these third party modules are used: HTML5lib, Reportlab and TG CSS Parser. All components are written in pure Python to ensure platform independency. More Informations on http://www.htmltopdf.org

This approach is very useful for web applications. Examples for integration with WSGI, Django, Turbogears, CherryPy and simple CGI are provided.

os.startfile is a windows only command. Other than that, works great.

Dose this work for complex web pages. I want to convert webpages directly to python. I tried to copy the html source of the webpage and inserted in the HTML TEST part. But it shows an error...Is there any way out of this ?
