I think you need to look for library functions or other built-in facilities. I thought the whole idea of Java was to get you away from low-level considerations of hardware and such. In any case you'd better hurry since both the traditional parallel port and it's cousin the RS-232 serial port are going away. Computer platforms are not being built with them any more.

 

Please look at this SITE or get the PARALLEL PORT COMPLETE book
