How to deny samba printing on certain queues?

That's the problem though: I don't want samba to be able to print to those queues, but other remote servers need to print to them.

Some of the servers are sending the print jobs through IPP, and others LPD.  I can't be guaranteed to get user or group information from those jobs, right?
