Following the link in the traceback I find the installation instruction for 
windows:

"""
Download the installer from the wkhtmltopdf downloads list and add folder 
with wkhtmltopdf binary to PATH.
"""

This PATH has nothing to do with Python's sys.path which specifies where 
Python looks for modules, and you have to set it according to the rules of 
your OS, e. g.

http://geekswithblogs.net/renso/archive/2009/10/21/how-to-set-the-windows-path-in-windows-7.aspx

Once you have added "the directory you had to cd into" follwing the above 
instructions your script should work in a newly opened shell window.
