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.
Communication with printer lost when connected to Virtual Private
Network (VPN)
You will lose your connection to a wireless printer on your local network when connected to most Virtual Private
Networks (VPNs). Most VPNs allow users to communicate with only the VPN and no other network at the same time.
If you would like to have the ability to connect to your local network and to a VPN at the same time, the system
support person for the VPN must enable split tunneling. Be aware that some organizations will not allow split
tunneling due to security or technical concerns.
