When to use the USB driver:

USB Driver is needed whenever data is to be sent/received from the printer using the USB interface. It is needed with both the Windows and the OPOS drivers, when these drivers use the USB interface as the underlying communication path. It is also needed if the application does not use either the OPOS or the Windows driver but needs to communicate directly with the printer using the USB interface.

When not to use the USB driver: USB driver is not needed if the communication viz. serial, parallel or

application uses any of the other forms of Ethernet, and does not use USB.
