driver. If the setup operation does not start, locate the Devices and Printers 
section in the Control Panel and select Add a Printer.
4. Select the printer model. 
Once completed, you should see the available printer on your host PC. You can 
adjust the printer’s USB settings using the instructions that follow.
USB Settings
The type (or class) of USB connection for the host must be determined. The follow-
ing USB connections are supported:
• CDC (Communication Device Class)
• Printer Class (Typical Windows
®
 Printer) 
•Composite (CDC/Printer Class)
Whenever possible, you should use the default setting, Composite (CDC/Printer 
Class), as it gives the most flexibility.  However, on some systems (e.g., handheld 
devices), CDC or Printer Class should be selected since handheld devices have lim-
ited support.
