One possibility might be pyparallel. (I haven't used it, but I have
used its sibling pyserial and found it very useful, and very usable.)

http://pyserial.sourceforge.net/pyparallel.html

"Short Introduction" sample code from the project's homepage:

    >>> import parallel
    >>> p = parallel.Parallel()     # open LPT1
    >>> p.setData(0x55)

Good luck!
