The printer can be connected to a PC or a handheld device using a USB cable. Before connecting the
printer to your host device, the type (or class) of USB connection must be determined. There are three
classes of USB connections that are supported:

CDC (Communication Device Class, virtual COM port via emulated RS-232)

Printer Class (Typical Windows Printer)

Composite Class (CDC + Printer Class)
Whenever possible, it is recommended to use the Composite Class, as it gives the most flexibility.
However, on some systems (e.g., handheld devices) CDC or Printer Class alone should be selected, as
handheld devices have limited support.
Software/Files Needed:
The following files can be downloaded from:
www.datamax-oneil.com

NETira CT Configuration Utility

Seagull Windows Drivers (for Printer and Composite Class installations only)

“Datamax-O'Neil Composite Class.inf” file (for Composite Class installations only)

“Datamax-O'Neil CDC Class.inf” file (for CDC installations only)
Create a new folder on your local computer named “Drivers”. Download the necessary files and place them
in this folder.
