parallel port no signal

I installed LinuxCNC via this ISO image onto a partition of my machine.

I've configured my machine but no signal is being sent to the parallel port.
I was able to control the machine using Grbl and my Arduino.
Any help on why there is no signal on the parallel port?

thanks tommylight,
I'm assuming you are referring to the "create simulated hardware configuration" check box which is unchecked but there is still no communication.

I just read another forum that suggested finding the lspci -v and after finding out what my port address was and entering it rather than leaving it 0. This Worked!!!
