If your using a Desktop PC, a simple inexpensive solution I have used is to buy a PC with at least one PCI or PCI express(narrow) expansion slot. You can purchase LPT cards for these slots for ~ 30ドル.00 . Install and configure the free Porttalk software (http://www.beyondlogic.org/porttalk/porttalk.htm_) and you will get a real LPT port that works with WL. Jim W7EJ
