I've had success interfacing with the serial port using the
win32serial library (http://grub.ath.cx/win32serial/). It uses a small
C program together with a ruby wrapper.

  require 'Win32Serial'
  @port = Win32Serial.new
  @port.open("COM1")
  @port.config(9600, 8, Win32Serial::NOPARITY,
Win32Serial::ONESTOPBIT)
  @port.timeouts(0, 200, 0, 0, 0)
  @port.write("test\r")

Perhaps this would give you a basis to build a parallel port
interface ?
