4.3 USB CONNECTORS
USB is a serial protocol and a physical link, which transmits all data on a single pair
of wires. Another pair provides power to downstream peripherals. The USB
standard specifies two types of connectors, type "A" connectors for upstream
connection to the host system, and type "B" connectors for downstream connection
to the USB device.

• Only one host computer is allowed for the USB connection.
• After starting a job using USB, do not switch the printer off until the job has been
completed. When a user cancels a print job, if data transmitted to the printer has
not been printed at the time of cancellation, the job will continue to print up to the
page where the print job was cancelled
• When the controller board is replaced, the host computer will recognize the
machine as a different device.
