USB communication is not supported through a network or extension device.  You would have to connect the printer directly to your computer if you wished to use the printer via USB.


The printer also has Wi-Fi capabilities.  You could connect the printer to a Wi-Fi router.  Next, make sure that the computer is on the same network and then reinstall the G4200 drivers for a wireless setup.  This should allow you to scan over the network.
