PrintDocument.Print Method (String)

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Starts the printing process for the specified document by opening the print dialog box.

Namespace: System.Windows.Printing
Assembly: System.Windows (in System.Windows.dll)

Syntax

'Declaration
Public Sub Print ( _
    documentName As String _
)

public void Print(
    string documentName
)

Parameters

documentName
Type: System.String
The name of the document to print.

Exceptions

Exception	Condition
SecurityException	The print operation is not user-initiated.

Remarks

In Silverlight 5 the printing defaults to vector printing. In Silverlight 4, the printing defaults to bitmap printing. You can specify bitmap printing in Silverlight 5 by using the PrintBitmap method.

Specify the output to print by handling the PrintPage event and by setting the PrintPageEventArgs.PageVisual property to the correct UIElement.

If the user cancels the print operation, the BeginPrint and EndPrint events will not occur.

Examples

The following code example shows a button event handler that calls the Print method and an event handler for the PrintPage event. In this example, an Image control, which contains a map, is printed.

Partial Public Class MainPage
    Inherits UserControl
    Private pd As PrintDocument()

    Public Sub New()
        InitializeComponent()
        pd = New PrintDocument()

    End Sub

    Private Sub PrintButton_Click(ByVal sender As Object, _
            ByVal e As RoutedEventArgs)
        pd.Print("M yMap")
    End Sub

    Private Sub pd_PrintPage(ByVal sender As Object, _
            ByVal e As PrintPageEventArgs) Handles pd.PrintPage
        e.PageVisual = mapImage
    End Sub
End Class

public partial class MainPage : UserControl
{
    PrintDocument pd; 

    public MainPage()
    {
        InitializeComponent();
        pd = new PrintDocument();
        pd.PrintPage += new EventHandler<PrintPageEventArgs>(pd_PrintPage);

    }

    private void PrintButton_Click(object sender, RoutedEventArgs e)
    {
      pd.Print("My Map");
    }

    void pd_PrintPage(object sender, PrintPageEventArgs e)
    {
        e.PageVisual = mapImage;
    }
}

<StackPanel x:Name="LayoutRoot">
      <Button Margin="5" Width="200" Content="Click to print" x:Name="PrintButton" 
              Click="PrintButton_Click" />
      <Image Width="600"  Height="600" Source="RedmondMap.jpg" x:Name="mapImage"/>
  </StackPanel>
