This one of those things that really should be in the interoperability test.
Not only should the 3 hr variables be read but also the subUnitStatus.
Variations would be to report the tray as "low" but the subUnitStatus report
Critical or you could ignore the text and say that there is tray out of paper
and that the printer has a warning.
