+/* 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.
