USB Connector Pin Assignments
SureMark printers contain a USB port, if the USB feature is installed. This port is on
the interface card, accessible under the printer without removing printer covers.
Connection to the port can be with either the standard USB Type B connector,
which requires a 24-volt power brick, or with the powered USB connector, which
contains 24-volt power lines within the communications cable.
The standard USB Type B connector has the following pin functions:
