For some reason you have no cups backends activated. Note that package updating keeps the current backend configuration, so you need to activate the backends manually. Please activated the backends again with this command: $ sudo dpkg-reconfigure cupsys By default all backends should be activated, for your usb printer the usb backend should definitely be activated.
