When you use a printer changer, printer buffer, or a extension
cable, the printer does not print correctly due to the combination
of these devices. Make sure that the printer works correctly when it
is connected to your computer without these devices.
The printer driver is not installed correctly.
Check that the printer driver is installed properly. If necessary,
reinstall the printer driver.

Confirm the USB setting is correct. See “Correcting USB Problems”
on page 111 for details.
