USB Interface
This printer supports USB v1.1 (also called USB 2.0 full speed).
To use the USB interface for printing from a PC, you need a
special Intermec USB printer driver installed in your PC.
The printer is a so-called “self-powered device.” We recommend
that you only connect one printer to each USB port on the host,
either directly or via a hub. Other devices, like a keyboard and a
mouse, can be connected to the same hub. If you need to connect
more than one Intermec USB printer to a host, you should use
different USB ports.
Using a USB Class A/B cable, connect the Class A plug to your
PC or hub and the Class B plug to your printer.
The USB interface is essentially a one-way communication
interface. There is no communication setup for the USB port.
