We're extending our internal network implemenation of Output Server to include integration of 3rd party warehouses via a Citrix type terminal server.
We're running Central Output Server 5.5. Our printer targets historically have all been pre-defined internal print queues. (\\<server>\<queue>. We need to extend this to encompass more dynamic printer targets that will appear on the Citrix clients.
Per Citrix support forums, people are doing this (can't really say how successfully as the forum does document issues).
