Jay,

Here are my thoughts...

Correct.

Actually, we have a situation where the printer has been told "stop
printing when the toner goes low because the user doesn't want to take a
chance on running out of toner." If the printer truly mapped the toner low
to a critical alert, it would never print with a low toner condition.

Toner low is implicitly a non-critical alert because technically, the
printer can still print with no degradation.

We aren't muddying up the table. We are just explaining a case where a
non-critical condition can cause a secondary critical condition. When the
critical condition is fixed (the printer is put online), the original
non-critical condition (toner low) remains.

I can agree to the above.

If the printer does this, then it appears as if the toner low condition was
fixed and then occurred again, when in reality the toner situation hasn't
changed. Also, this causes the management application to handle yet another
alert (three instead of two).

Just the above.
