/* Zugriff auf den Drucker sollte ausschliesslich ueber diese Klasse erfolgen
 * ==========================================================================
 *
 * Der Drucker kann dem Dokument oder auch dem OLE-Container gehoeren. Wenn
 * das Dokument also eine OLE-Dokument ist, so gehoert der Drucker auch
 * grundsaetzlich dem Container. Der Container arbeitet aber eventuell mit
 * einer anderen MapUnit als der Server. Der Drucker wird bezueglich des MapMode
 * im Konstruktor entsprechend eingestellt und im Destruktor wieder restauriert.
 * Das bedingt natuerlich, das diese Klasse immer nur kurze Zeit existieren darf
 * (etwa waehrend des Paints).
 * Die Kontrolle darueber ob der Drucker selbst angelegt, vom Server besorgt
 * oder dann auch NULL ist, uebernimmt die DocShell in der Methode GetPrt(),
 * fuer die der Access auch Friend der DocShell ist.
