Correcting USB Problems
If you are having difficulty using printer with a USB connection, see if your problem is listed below,
and take any recommended actions.
USB connections

multiple USB hubs, we recommend that you connect the printer to the first-tier hub.

driver on a computer that does not meet these specifications or that is not equipped with a built-in
USB port.
