Ejemplos

En el ejemplo de código siguiente se imprime un documento con la primera página en color, si la impresora la admite. En el ejemplo se supone que se ha creado una PrintDocument variable denominada printDoc y se controlan los PrintPage eventos y QueryPageSettings .

Use los System.Drawing espacios de nombres y System.Drawing.Printing para este ejemplo.

private:
   void MyButtonPrint_OnClick( Object^ sender, System::EventArgs^ e )
   {
      // Set the printer name and ensure it is valid. If not, provide a message to the user.
      printDoc->PrinterSettings->PrinterName = "\\mynetworkprinter";
      if ( printDoc->PrinterSettings->IsValid )
      {
         // If the printer supports printing in color, then override the printer's default behavior.
         if ( printDoc->PrinterSettings->SupportsColor )
         {

            printDoc->DefaultPageSettings->Color = false;
         }

Es posible imprimir cada página de un documento mediante una configuración de página diferente. Para establecer la configuración de página, modifique las propiedades individuales de la PageSettings propiedad o establezca la propiedad en .PageSettings El trabajo de impresión también se puede cancelar estableciendo la Cancel propiedad en true.
