It's not just about sharing between a printer(device) and your PC.
It is a limit configuration not unlike the "mem=" kernel parameter, but
for a different propose/control.

The following link might explain the term a better
<http://www.opensolaris.org/os/community/arc/caselog/2006/496/spec-txt/>

	capped-memory
		physical: A positive decimal number with a required k, m, g,
			or t modifier.  A value of '10m' means ten megabytes.
			This will be used by rcapd as the max-rss for the
			zone.  The rcapd enhancement for capping zones is
			described below in section 4.

		virtual: This property is tentative at this point and will not
			be delivered as part of this project.  However, our
			thinking on this is described here for completeness.
			In the future we would like to deliver a new rctl
			which would cap the virtual memory consumption of
			the zone.  The name 'virtual' is not necessarily the
			final name.
