Question about Brother MFC-J4340DW

Yes, you can configure a NAS so that you can scan directly to a share. This is often referred to as "scan-to-NAS" or "scan-to-file". To enable this, you need to adjust the network settings of your printer and create a user on the NAS who has the necessary permissions. You can then set the printer so that it can scan directly to the NAS share. Brother devices support this function via the network options in the device menu.
