Interfacing hardware is something I do often- although I've never had to
worry about parallel ports.

1. What OS are you using ?  If NT/2000 you will need a device driver to get
access to the port.  They are available off the web.  I have never used
http://www.winsoft.sk/ioport.htm but have been told it is good.

2. As for the hardware you need to determine if there is a protocol offered
by the manufacturer, or better still, if they have an existing interface
(such as a DLL) that you can use directly.
