Hi Carlos.
Actually I believe that the sampling rate of those cards won’t be enough to monitor the parallel port. Usually the parallel port can communicate at different speeds that go from 360,360 to 2,500,000 bits per second.
The NI USB 6009,NI USB 6501 or the NI USB 6525 do not work at the sufficient speed for monitoring the parallel port.
I found another discussion that talks about this issue, so it may be a good idea that you take a look at it.

Hope this helps.
Have a nice day.
