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, then try one or more of the following:
•
Update the firewall using the most recent update available from the manufacturer. For instructions on how to
do this, see the documentation that came with your firewall.
•
If programs request firewall access when you install the printer or try to print, then make sure you allow those
programs to run.
•
Temporarily disable the firewall, and then install the wireless printer on the computer. Re-enable the firewall
when you have completed the wireless installation.
