They do in my environment, but that's because hardware was scarce. Be aware, when NPrinting does it's thing, it will act like SQL Server and try to eat up all the RAM (It sees a byte, it eats a byte). For a while, this was making the server unresponsive to requests from users, as well as putting a crimp in any data/dashboard reloads that were occurring.
If at all possible, stuff your NPrinting onto another server. But if you are on a budget, rollin' with servers picked up at Dollar General, then you have no choice and will have to help users manage their expectations.
