/* 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.
