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