•
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.
