The Brother MFC-9330CDW is a color laser all-in-one printer (with printing, scanning, copying, and faxing capabilities) designed for both home and small office environments. The Remote Setup Port is typically part of the software package that allows users to configure the printer remotely or use it in a networked environment (either via USB or over a network like Wi-Fi or Ethernet). The Windows driver is the software required to make the printer work with your Windows operating system, enabling communication between the printer and your computer.
