User quotas on particular printer

I need to set up a printing quota system on a particular printer. I’ve a network with 35 clients (200 users sharing these) and some b&w printers and a networked color laser printer. Users tend to print without even knowing what they are doing and therefore I need to set printerquotas for the users on the color printer. This printer has a NIC, but it is installed only on a Win2000 server, and shared from that server. How can I limit certain users preferably by group membership?
