I don't know too much about perl, but I do know i/o and os stuff. The parallel port is an i/o resource and is only accesible by privilidged code (ie the operating system's device drivers). If you can use unix system calls from perl, then you can ask unix (i assume linux) to write and read the port for you. Just find out what file represents the parallel port and open a file descriptor for that file.
