NT Printer Sharing

Shared a number of printers on NT Server. Have Win98 clients connecting – so I opted to “add” drivers for Win98. Got updated drivers now. How do I update the Win98 drivers on the NT server? I know once done, I have to remove/reinstall the printers on the Win98 machines to use the new drivers – but how do I replace the old drivers NT is sharing out?

I have already stopped sharing on a printer, restarted sharing, then it prompted me for drivers and I was able to point to the new ones. But thistakes the printer off-line as I have to “unshare” it. Is there another way to do this that won’t require me to stop and restart printer sharing?
