I am trying to share a Brother HL-2140 printer connected to a Windows 7 64 bit computer on a WORKGROUP with an older 32 bit VISTA computer. When I try to change the printer setting to "Shared" and save or apply it, I get a message "Printer Setting cannot be saved error 0x000006d9".

Hi, I would like to suggest you refer to the following link to make sure your firewall allows file and printer sharing: http://windows.microsoft.com/en-US/windows7/Networking-home-computers-running-different-versions-of-Windows Regards,Arthur Li - MSFT
