In trying undock my laptop, I kept getting the message that the undocking procedure could not be accomplished because of a program running using LPT1. I could not find such a program running, so as a test, I went to Device Manager and disabled LPT1. That worked regarding being able to safely undock my laptop. BUT, now I want to enable LPT1 for an older printer at another location. AND, I cannot find LPT1 in Device Manager to Enable it! I have searched and searched and can no longer find any reference to it as I could before when I Disabled it. What am I probably doing wrong! How do I proceed? Thanks!
