When a remote user initiates a connection to your local printer, the signal passes through your computer’s network ports and your security software checks it. A McAfee firewall blocks these network ports by default, which can prevent printer sharing by making your printer virtually invisible. To enable printer access, you’ll need to create an exception that opens the firewall and allows the connection to pass through to your printer. You can create a special permission rule in the McAfee security software that allows you to share your printer with other users on your network. Warnings Writer Bio
