Lexmark 7600 Series - Manual (Page 151)

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, 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.
