Some have asked how to operate a Brother MFC-8860DN printer with a PC using Win11 when Brother does not supply a Win11 driver, and Win11 will not recognize Brother's last available driver, for Win10. I have found that Brother's operating suite for the MFC-8860DN, Control Center 3, available as a download from Brother for the Win7-64 OS, will allow the MFC-8860DN to receive both print and scan commands in Win11, when the MFC-8860DN is connected via a LAN. Win10 PCs can also communicate with the printer in CC3 over the same LAN. Hope this helps somebody.
