Reason for change:
The original text would seem to require all printers to respond
identically in hrDeviceStatus on the same error condition. Reality
is that different printers respond differently on the same error
condition. What might be a warning in one printer may be a down
condition in another printer. Even within a printer a single error
condition might be a warning one time and a down condition another
time. For example, several printers support the linking of multiple
paper trays together to form one logical paper tray, when one of the
linked trays runs out of paper the printer will start feeding paper
from one of the other linked trays, the printer may report noPaper
but it is a warning condition because paper is being fed from
another tray.
