How can-I read from the parallel port ? (LPT1)

(I want to read the output of an application to the parallel printer device. So I connect the parallel cable to my computer, and I expect to be able to read the parallel port as a normal file with the 'open' command. But .. nothing happens ... WHY ?)

Any help is wellcome ... thanks.
