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.
