PrnOffset( hDC )-> <aPoint>
------------------------------------------------------------------------------


 PARAMETER:

  <hDC>          Handle that identifies the printer device context


 RETURNS:

  <aPoint is an Array with the offset values { x, y }, that will receive
  the printing offset (in the current orientation). The x member receives
  the horizontal coordinate of the printing offset, in device units, and the
  y member receives the vertical coordinate of the printing offset, in
  device units. 


 DESCRIPTION:

  The PrnOffset function retrieves the offset from the upper-left corner of
  the physical page where the actual printing or drawing begins. This escape
  is generally not useful for devices that allow the user to set the origin
  of the printable area directly.
