Capturing Parallel Port Data

I have been reading the ppi man page and have searched Google but have not
found an answer to my problem: I work at a business which uses cable
testers that output plain text to a dot matrix printer (any old DMP will
work). (Cirris cable testers) The paper trail is getting huge so I am
trying to write a program that does the following:
Prompts the user for the cable part number
Reads data from the parallel port, which is connected to the parallel output
of a Cirris tester
Prompts for any notes regarding the cable
Inputs the data into a database table
Now, my real question is: how do I read data from the parallel port on the
FreeBSD computer that is coming from the tester which is trying to 'print'
to the FBSD computer's parallel port? Is there a suggested pinout for a
parallel crossover calbe to accomplish this task with ppi? Is the crossover
cable even required?
Finally, is there a FBSD-sanctioned parallel port driver for use with Perl
instead of using ppi and C?
Any and all help is welcomed and apriciated.
