I believe that if a tray is out of paper, then something should be reported in
the host resources table. It has been my experience that is better to provide
as much information as possible and then let the management app decide. We
should however, try to clear up as much of the mib as possible.
What should be reported in the following situations: a priner has legal in a
200 sheet tray but the two thousand sheet tray that is supposed to have letter
in it is empty. If a job want letter paper then in all probablity the printer
is going to stall waiting for letter to be loaded. If the printer has stalled
then it is in an error state, no paper. But what about if it is not stalled
waiting on the tray(say it pick the last sheet as the last page of the previous
job)? If the three hr variables are supposed to reflect the state of the
printer, and a management app is looking to those variable to keep it informed,
then they must report somethng, but what is the right answer?
