Centralizing iPrint Printers

We are planning to migrate 8 different iPrint sites on our WAN running
different IP address ranges to 1 centralized iPrint server running oes2
Linux. Is it possible to migrate all those site's printers to 1 NDPS Broker
and Manager or would 8 different NDPS Brokers and Managers need to be
created in order to accomdate the printers running at the different sites?
