can't print after install

Since installing Comodo Firewall my laptop no longer prints over the wireless network. From the Vista Control Panel the computer sees there is a shared printer. I have reinstalled the HP psc 2175 softewware, ran thhe share printer and network set up wizards and still it won’t print even with the firewall disabled. What has Comodo done to my configuration to block my print jobs?
