Tiger printserver – making jobs hop to different printer queue

Hi. i am sitting for the 2nd day at a location with 200 users with network home directories on a G5 running tiger server. It turns out that simply making a printer queue and sharing it out with printserver will not prevent the users from printiong directly to the printer, in fact they do so by default. i gather this is because the home directories are located on the same server as the printserver. They just use the printers in the printcenter, bypassing the server. the solution, I have been told, is to set up one printer, say an IPP printer with the printers IP. Then, make another printer with the servers IP, and share that "printer". The jobs should then hop from the server "printer" to the actual printer that only the server can see. I cannot for the life of me figure out how to make the jobs hop from the server ip adress "printer" to the real printer. all I know is that it is a way to do this, because it was set up that way before the server was formatted. does anyone know the solution to this, the folks here is really getting rather angry! Help!
