Windows 10 firewall blocking Brother printers

Firewalls monitor network traffic and can block network connections for some programs and hardware. Windows 10 includes its own Windows Defender Firewall that might block Brother printers and other models for some users. Thus, the affected users can’t utilize their Brother printers when firewalls block them.

Why is Windows Firewall blocking my printer?

1. Turn Off the Windows 10 Firewall

  1. The most obvious, and perhaps straightforward, way to stop Windows Defender Firewall blocking a printer is to turn off WDF. Users can do that in Windows 10 by clicking the Type here to search button on the taskbar.
