Managing Windows shared printers

Hi,
We are making tests with CUPS on a Linux Conectiva 10 server.
The problem is that we have some printers shared in stations windows 9x/2k. We can share these saw CUPS, but if the user map the printer and print direct the CUPS does not obtain to manage the job.
There any way to listen the printer and remove the jobs not authorized or make the CUPS to interpret them and later sending them again, now under an impression saw CUPS.
