Installing the printer driver
To identify terminals connected via USB interface, the PC requires the corresponding
virtual USB devices to be implemented by driver. If you connect any number of printers to
your PC, therefore, the same number of virtual USB devices will be automatically
configured on your PC. To prevent virtual USB devices from being configured limitlessly,
use the unique driver installation procedure described below that enables your PC to
identify terminals via single virtual USB device.
NOTE:
Once this installation procedure is carried out for the PC, no more driver installation will be
required for that PC to identify machines.
1. Unplug the USB cable, if the printer is connected to the PC.

* The printer goes back to the normal mode automatically when the printer remains
no operation while the Status LED is lighting.
