USB driver
A USB driver is a low level device driver, required for USB communication with the
printers. It is a Windows Plug and Play driver and needs to be installed for USB printers,
when the printer is initially plugged into the system.
Figure 7 USB Driver
When to use the USB driver:
A USB driver is needed whenever data is to be sent to or 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:
A USB driver is not needed if the application uses any of the other forms of
communication such as serial, parallel, or Ethernet, and does not use USB.
