Unable to print from remote desktop computer

Looks like CIS is only for basic users. I’ve only had it a couple days and have already had 2 serious problems. Can’t use second LAN card, and now I can’t print from a computer that I am remoted into via Windows Remote Desktop. I clicked PRINT then got an alert from CIS which I allowed. Even so, all further attempts to print fail. My last firewall, Online Armor, had no problems in any areas.
