RS-232 Serial Cable DB9 Pins
USB Interface
The printer supports USB full speed v2.0 Host. To use the USB interface to print
from a PC, you need to have the Honeywell printer driver installed on your PC. For
help setting up USB communications, see "Connecting the Printer to a PC Through
the USB Device Port" on page 50.
The printer is a “self-powered device.” Only connect one printer to each USB port
on the PC, either directly or through a hub. You can connect other devices, such as
a keyboard or a mouse, to the same hub. If you need more than one USB printer to a
host, you should use different USB ports.
