The current level if this supply is a container; the
remaining space if this supply is a receptacle. If this
supply container/receptacle can reliably sense this
value, the value is reported by the printer and is
read-only; otherwise, the value may be written (by a
Remote Control Panel or a Management Application). The
value (-1) means other and specifically indicates that
the sub-unit places no restrictions on this parameter.
The value (-2) means unknown. A value of (-3) means that the
printer knows that there is some supply/remaining space,
respectively.
