Access directly to the parallel port under linux is only possible if you
are part of the kernel... ie- you need to patch into the kernel to pull
that off... ouch.
Why not take a look at this package:
http://www.circlemud.org/~jelson/software/parapin/
It shows both methods of accessing the parallel port, user space and
kernel space. Even if you decide not to use this package, it will at least
get you started in the right direction.
