Comentarios

Cuando se crea una instancia de PrintDialog, se establecen las propiedades de lectura y escritura en sus valores iniciales. Para obtener una lista de esos valores, vea el constructor PrintDialog. Para obtener la configuración de impresora que el usuario ha modificado con PrintDialog, utilice la propiedad PrinterSettings.

NotaNota:

Esta clase quizá no funcione en los microprocesadores AMD64 a menos que se establezca la propiedad UseEXDialog en true.

NotaNota:

Los miembros contenidos en esta clase se utilizan al imprimir desde una aplicación de formularios Windows Forms. Si está imprimiendo desde una aplicación Windows Presentation Foundation, vea Printing Overview

Ejemplo

En el ejemplo de código siguiente se muestra cómo utilizar el control PrintDialog para establecer las propiedades AllowSomePages, ShowHelp y Document. Para ejecutar este ejemplo, pegue el siguiente código en un formulario que contiene un control PrintDialog denominado PrintDialog1 y un botón denominado Button1. En este ejemplo se requiere que el evento Click del botón y el evento PrintPage de docToPrint se hayan conectado a los métodos de control de eventos definidos en este ejemplo.

Visual Basic
' Declare the PrintDocument object.
Private WithEvents docToPrint As New Printing.PrintDocument

' This method will set properties on the PrintDialog object and
' then display the dialog.
Private Sub Button1_Click(ByVal sender As System.Object, _
    ByVal e As System.EventArgs) Handles Button1.Click

    ' Allow the user to choose the page range he or she would
    ' like to print.
    PrintDialog1.AllowSomePages = True

    ' Show the help button.
    PrintDialog1.ShowHelp = True

    ' Set the Document property to the PrintDocument for 
    ' which the PrintPage Event has been handled. To display the
    ' dialog, either this property or the PrinterSettings property 
    ' must be set 
    PrintDialog1.Document = docToPrint

    Dim result As DialogResult = PrintDialog1.ShowDialog()

    ' If the result is OK then print the document.
    If (result = DialogResult.OK) Then
        docToPrint.Print()
    End If

End Sub

' The PrintDialog will print the document
' by handling the document's PrintPage event.
Private Sub document_PrintPage(ByVal sender As Object, _
   ByVal e As System.Drawing.Printing.PrintPageEventArgs) _
       Handles docToPrint.PrintPage

    ' Insert code to render the page here.
    ' This code will be called when the control is drawn.

    ' The following code will render a simple
    ' message on the printed document.
    Dim text As String = "In document_PrintPage method."
    Dim printFont As New System.Drawing.Font _
        ("Arial", 35, System.Drawing.FontStyle.Regular)

    ' Draw the content.
    e.Graphics.DrawString(text, printFont, _
