    Parallel port initialization as non administrator

    Hi everyone,

    I have a computer here running Windows XP that its sole purpose is to run PlasmaCAM, an application that talks to a plasma cutter in the shop via parallel port. If a local administrator initializes the plasma cutter in the PlasmaCAM software, the machine initializes and works fine, and if I log in as a standard network user account, the machine initializes and works fine. BUT, if I restart the computer and log in as a standard user right away and try to initialize the machine, I get an error message that says "could not start port access driver" and I believe "code 2".

    Nothing shows up in the Event Viewer logs, but I can only imagine that some parallel driver needs to start at boot and is currently set to manual and only started when I initialize the PlasmaCAM machine as an administrator.

    What's bugging me most is I seem to have fixed this on a past machine and it WAS working, albeit with a PCI parallel card and not an internal parallel port, but I can't figure out what I did, or if the simple fact of running a PCI card instead of internal was enough to fix it. Any advice on how to start this "access driver" on boot up would be much appreciated.

    Thanks!
