Okay, I've dug around here and determined that this capability is going
to be included in the next release of OES. I've also learned that until
then the best solution is pcounter.

My question is that in iManager, Manage Printer, Configuration,
default(legacy) there is a setting called 'Max copies', which tells me
that I should be able to limit it. However, even setting that to '1' and
restarting the printer doesn't do it. I can still print 3 copies.

What gives here?
