Total number of PCL pages printed by the device.
Additional information:
In LaserJet 4050 Series the PCL page count is kept in
NVRAM, and the NVRAM value is updated at least every
10 pages. NOTE: The value returned by this object will
be incremented every page but if power is lost between
NVRAM updates, up to 9 pages of the page count may be
lost. The page count counter will be reset to zero
after 16,777,215 (2^24-1) pages.
The page count is incremented when a sheet of media is pulled from an input
tray. A duplex printed sheet will cause this counter to be incremented by
two.
