   * Data Members
   * Each of these data members make a copy 
   * of the contents. If you get the value, 
   * you own the memory.
   * The following three pieces of data are needed
   * to create a DC for printing. These are typcially 
   * gotten via the PrintDLG call ro can be obtained
   * via the "m_pd" data member of the CPrintDialog
   * in MFC.

   * On Windows we use the printable width and height for the printing surface.
   * We don't want to have to create native print device contexts in the content
   * process, so we need to store these in the settings.
   * Storing in Inches is most convenient as they are retrieved from the device
   * using fields which are in pixels and pixels per inch.
   * Note these are stored in portrait format to ensure that we can take account
   * of our own changes to the orientation print setting.
