Connecting Kernel Mode Driver ISR to IRQ7 of ParallelPort

Hi
I need to connect in my Kernel Mode Port Driver an ISR to IRQ7[for ACK
change from 1 to 0] of ParallelPort.
My Kernel Mode Port Driver is for a Device connected to parallel port which
generates interrupt and is wired to
ACK pin of parallel port.
any ways to do it?
thanks,
