[Zope] html2pdf

I am trying to use html2pdf and htmldoc to generate pdfs on the fly. I can get it to work perfectly if I set all view permissions for anonymous. However, this is not suitable for a member only site. Can anyone point me in the right direction for such use? I am using: (Zope 2.9.0, python 2.4.2, win32) and latest version of html2pdf. Regards Garry
