Beispiele

Im folgenden Codebeispiel wird ein Dokument mit der ersten Seite in Farbe gedruckt, sofern dies vom Drucker unterstützt wird. Das Beispiel erfordert, dass eine PrintDocument Variable mit dem Namen printDoc erstellt wurde und die PrintPage Ereignisse und QueryPageSettings behandelt werden.

Verwenden Sie die System.Drawing Namespaces und System.Drawing.Printing für dieses Beispiel.
