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