  52 /* Access to printer should happen through this class only
  53  * ==========================================================================
  54  *
  55  * The printer can belong to the document or the OLE-Container. If the document
  56  * is an OLE-Document the printer generally belongs to the container too.
  57  * But the container maybe works with a different MapUnit than the server.
  58  * Referring to the MapMode the printer will be accordingly adjusted in the
  59  * constructor and restored in the destructor. This brings that this class
  60  * is always allowed to exists only a short time (e.g. while painting).
  61  * The control whether the printer is self-generated, gotten from the server
  62  * or is NULL then, is taken by the DocShell in the method GetPrt(), for
  63  * which the access is friend of the DocShell too.
