Take a look at libieee1284: http://cyberelk.net/tim/libieee1284/. It
is a nicer interface to the kernel ppdev driver, which also has some
fall-back I/O routines if ppdev isn't available. It is meant to be
cross-platform-capable, and for example I don't think it would take
too much effort to get it going on *BSD.
For Linux, ppdev is available in the 2.4.x kernel series.
