what have you tried to do and what issues are you running into?
looks like the easiest way to do it is to
run the install software on the computer and then tell it that it is a network printer and attach a usb cable between the printer and the computer while the install runs
it says to put the usb cable on first but my experience is that you are better off starting the install and letting it tell you it cant find the printer attach the cable
that keeps windows from installing it as a usb printer.
