Hmm, after reading the story, I can't really come up with a solution.

With a small headphone with a resistor of 10k to 47k placed serial, you
can 'hear' the activity on the LPT port. I use this trick a lot to
analyse hardware problems. Using the headphone you can determine if
there is any activity on the LPT port at all.
