Printserver and DMZ

We just build an NT Server that we put in the DMZ. I am wondering, we are trying to connect to a printer creating a printerport and opening a whole in the firewall to connect to it. We are able to see the job go in the printer, but it doesn’t print.Can you specify more than one printserver for 1 printer (all drivers and everything works). Where did the job go? It didn’t print to the file, it dissapeared in DMZ land.

Can you help?
