Re: test_with_parallel_port

Make sure your parallel port is set up in the BIOS to be in standard mode, and 
not EPP or any other enhanced mode.

Make sure your pins aren't loaded down either.  For a project I did a few 
years ago using comedi and the parallel port, I had to add in some transistor 
circuitry to be able to drive the relays as my parallel port only could 
source about 5 ma of current.
