Look at the TVicLPT component

http://www.entechtaiwan.com/tviclpt.htm

It gives you complete control (including an LPT interrupt event) over
the parallel port. You can treat the port as a parallel port, a
printer port or as individual pins to set high or low or read their
input state. There is a free version to try out and it's inexpensive
to buy. It will even find parallel ports installed at the high
addresses that the PCI bus and Windows XP insist on (in addition to
the old DOS locations of 278 h, 378 h and 3bc h).
