NW 6.5 SP4

I just installed a new NDPS and created a broker & manager on my server. I then created several printers via iManager 2.5 like I normally would do. I'd like to use the "direct print" feature to minimize network traffic, so I enabled it. Then I installed the printers and all of they continuously say "connecting" or "error". So it does not work.

Anyone have any suggestions? How do I even know that it's enabled - the NDPS manager says the queue is still on the server.
