I have Parallels 9 installed and running on a Mac Air with Windows 7 Pro as the guest OS. I have the USB connection set to connect to the Guest OS(Win7) and it every time the printer is power cycled or the Win7 OS is rebooted the virtual port changes. This causes it to install a 'Copy' of the printer which it being a receipt printer, the POS software fails to recognize the copy. Is there a way to make sure the virtual port stops changing?
