When you installed the printer drivers in the beginning you had the printer plugged in to the port that now works. If you open the PRINTERS icon in Control Panel, and then access PROPERTIES for the printer, then click on PORTS you will see the specific USB address in the list of ports.
If you must use another port then uninstall the printer driver, plug the printer in to another USB port, then reinstall the printer drivers.
Some people just gotta be a stick in the mud....
Dude. You just HAD to go and give a serious sensible answer in the midst of all our fun.
Killjoy.
