The make and model of the USB to LPT device might reveal more details.
Also why "not a printer"? If it's some dongle you can use a PCI parallel port (I use the Lava.)
Wondering if anybody have a solution to this one:
I have a usb docking station that has parallel port as one of the ports and I also tried USB to parallel cable.
USB to parallel port Usually windows XP add a USB printing service and doesn't show virtual LPT port at all and the software that i am using doesn't like that it needs to see LPT port "Not a printer by the way"
and now most of the laptops including mine doesn't have a parallel port.
By the way I installed Windows 98 SE on the laptop trying to figure out where is the problem and Windows 98 worked perfectly and showed the LPT port after I showed it the Driver.
Windows XP will not take the driver and it has to use it's own.
