The Brother MFC-8890DW is a multifunction printer (MFP) that supports printing, scanning, and faxing, and it can connect to your computer via a network connection (LAN), USB, or wireless. The LAN Windows driver refers to the printer driver that allows your computer running Windows to communicate with the printer over a Local Area Network (LAN) connection.
To use the printer over a LAN connection (Ethernet or Wi-Fi), you need to install the appropriate driver on your Windows computer. This driver ensures that your computer can properly send print jobs, scan documents, and manage the printer's settings over the network.
