The count of the number of units of measure counted during
the life of printer using units of measure as specified by
prtMarkerCounterUnit.
Additional information:
This is the equivalent of the total page count.
The count is updated
each sheet of media. If duplexing is on, this counter will be incremented by 2.
The valid range of this object is 0 to 2^24 -1. When the number of pages printed exceeds maximum page
count, the value will roll to zero. (Realistically, this should never happen since that value more than 16 times
the rated life of the engine.)
