.. Your Brother Printer Works Only When Firewall Is Off? 👉 1-866-490-0338(USA/UK) ☎️
If your Brother printer prints only after you disable the firewall, the printer is probably not broken. The firewall is blocking the network communication between your computer and the Brother machine. This can happen after a Windows update, new router setup, antivirus installation, driver reinstall, or moving from USB to Wi-Fi printing.
The wrong fix is to leave the firewall turned off. That may restore printing, but it also weakens your computer’s network protection. The better fix is to allow Brother printing and scanning through the firewall using safe exceptions.
This guide explains **setup Brother printer through firewall** steps for Windows users, plus scanning, third-party antivirus firewall, and driver reinstall fixes.
