Firewall causing Printer Problem

Hello,

I recently installed Comodo firewall v3 and now suddenly my printers connected via print server are not working. I exited the firewall but they are nolonger detected by my computer even with the firewall off! What happened and what can I do to re-establish connection with my printers.

Thanks for any help
