So, I finally got my Brother 5340D printer to work in an old Windows 98 environment. I know, I know - who uses that any more? My boss...that is who. Anyway, I found that using the Brother HL-6 device drivers in Windows 98 works with the Brother 5340D printer...except it does not allow for duplex printing. Has ANYONE else figured out a way to get this printer to work in Windows 98 with duplex? Thank you.
