Netware 6.5 SP7

We have around 250 printer agents with driver profiles configured for
Mac and Win XP. I have just upgraded the server form SP5 to SP7 with the
above patch. This gives Vista users the opportunity to print to our
iprint printers with the iprint client rather than the below workaround
that they have been using -

The advantage of the workaround is that Vista uses the locally available
drivers. If we were to start using the iprint client then all the driver
s would need to be uploaded to the server and associated to the 250
printers for Vista manually.

Is there any way of bulk uploading the drivers, or bulk associating the
drivers to printers, or is the broker database a closed book and
everything has to be done manually, which would be very painful?
