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.
