Currently I believe you have to use NRM to "manage" your existing NDPS
Managers (ie, see which printer agents are having problems, clear print
jobs, shut down printers, etc.)

But I don't see a way to "limit" this (ie, either you have full admin
rights in NRM or you don't).

Is there any way to accomplish this in iPrint via NRM or iManager?

The iManager plugins seem mainly for creating the printers and managers,
and not actually "managing" them (the printer agents anyway).

Or am I missing something?
