Pushing Network Printers via GPO

I am attempting to us a GPO (and batch file) to push network printers to
client workstations. The batch file is using the rundll32
printui.dll,PrintUIEntry command. The first time the pc runs the batch file,
the printers are installed, but that is not the problem. I don't want the pc
to try and seach AD everytime it logs in looking for these printers, i only
want it to do it once. Once the printers are installed, i don't want it to
try and install them again everytime the pc starts. I'm assuming there is an
additional switch that needs to be added to my batch file, but i just don't
know what it would be. I have tried several different ones, but can't find
the right now. Does anyone know? Thanks.
