Artikel
08/20/2007

Startet den Druckvorgang für das Dokument.

Namespace: System.Drawing.Printing
Assembly: System.Drawing (in system.drawing.dll)

Syntax

'Declaration
Public Sub Print
'Usage
Dim instance As PrintDocument

instance.Print

public void Print ()

public:
void Print ()

public void Print ()

public function Print ()

Ausnahmen

Ausnahmetyp	Bedingung
InvalidPrinterException	Der in der PrinterSettings.PrinterName-Eigenschaft bezeichnete Drucker ist nicht vorhanden.

Hinweise

Geben Sie die zu druckende Ausgabe an, indem Sie das PrintPage-Ereignis behandeln und die in PrintPageEventArgs enthaltene Instanz von Graphics verwenden.

Geben Sie mit der PrinterSettings.PrinterName-Eigenschaft an, auf welchem Drucker das Dokument gedruckt werden soll.

Die Print-Methode druckt das Dokument ohne Verwendung eines Dialogfelds. Verwenden Sie einen PrintDialog, wenn Sie den Benutzern das Auswählen von Druckoptionen ermöglichen möchten.

Hinweis

Wenn während des Druckvorgangs eine Ausnahme ausgelöst wird, die nicht von der Print-Methode behandelt wird, wird das Drucken des Dokuments abgebrochen.

Beispiel

Im folgenden Codebeispiel wird die über die Befehlszeile angegebene Datei auf dem Standarddrucker gedruckt.

Hinweis

In diesem Beispiel darf keine Zeile die Seitenbreite überschreiten.

Verwenden Sie für dieses Beispiel die folgenden Namespaces: System.ComponentModel, System.Drawing, System.Drawing.Printing, System.IO und System.Windows.Forms.
