I used to use the XP firewall (behind my hardware firewall), and decided to try the fine Comodo offering. All is fine, except I don’t know how to configure Comodo to allow my wireless laptop to print through my Desktop to my printer which is cabled to my Desktop. With the XP firewall, all I had to do was Share the printer, then enable the File and Print Sharing on the XP firewall. I don’t have Comodo on the laptop, only on the Desktop.
