Cannot print and there is a firewall on the computer

Third‑party (non‑Microsoft) firewalls can interfere with wireless printing. If the printer and computer are configured
correctly, and the wireless network is working, but the printer will not print wirelessly, then a firewall could be the
problem. If there is a firewall (other than the Windows firewall) on the computer, try one or more of the following:
•
Update the firewall using the most recent update available from the manufacturer. Refer to the documentation
that came with your firewall for instructions on how to do this.
•
If programs request firewall access when you install the printer or try to print, make sure you allow those programs
to run.
•
Temporarily disable the firewall and install the wireless printer on the computer. Re‑enable the firewall when you
have completed the wireless installation.
