I have checked and tried all of above, however the Brother printer does not print. Is there anything else I can do? Uninstall the RJ-4040 installer and reinstall it. I'm using security software. Question Did you choose to accept the security alert dialog during the standard installation or BRAdmin Light installation or when using the printing features? I want to know the necessary port number for the security software settings. Solution If you did not choose to accept the security alert dialog, the firewall function of your security software may be rejecting access. Some security software might block access without showing a security alert dialog. To allow access, see the instructions of your security software or ask the manufacturer. The following port numbers are used for Brother network features:  BRAdmin Light i Port number 161 / Protocol UDP For details on how to open the port, see the instructions of the security software or ask the manufacturer. 15
