If the printer is turned OFF and back ON after changing the USB
ID, the computer (Windows) detects the USB port used to connect
the printer as a new port and automatically copies the printer
driver as xxxx (Printer Name). If you need to perform another
adjustment using this tool, select the “copy x” driver next time.
