Printer permission in RDS envirement

I have a problem in the print management in a multi-site environment, where all users use remote desktop sessions on a HQ server (Win2012R2).

All printers are network printers, installed with TCP/IP protocol on a print server (Win2012R2), in HQ, with the RDS Server.

I need to prevent users to print on printers in other locations, but only on printers in their seats.

How do I set permissions on printers, printer server or RDS Server to make sure that users in site A, don't use printers in site B?

Thanks a lot
