Then such a printer shall implement the conditionally mandatory
pending state. But an implementation that never waited a human perceptible
time should not have to implement the 'pending' state. Imagine that you
are building a product that is going to be tested against by a testing
company. If 'pending' is mandatory and your product doesn't ever show
'pending', that testing company might say you didn't conform to the
standard.

If we spend much more time discussing this issue, it may be wiser to take
your suggestion and make 'pending' mandatory.
