Classe PrintPreviewControl
Representa a parte de visualização de impressão de um aplicativo Windows Forms, sem caixas de diálogo ou botões de visualização não processados. A maioria dos PrintPreviewControl objetos são encontrados em PrintPreviewDialog objetos, mas não precisa ser.
Assembly: System.Windows.Forms (em System.Windows.Forms.dll)
Quando você cria uma instância do PrintPreviewControl classe, algumas das propriedades de leitura/gravar são conjunto valores iniciais. Para obter uma lista desses valores, consulte o PrintPreviewControl construtor.
Para obter mais informações sobre como imprimir com o Windows Forms, consulte o System.Drawing.Printing namespace Visão geral. Se você quiser imprimir a partir de um aplicativo Windows Presentation Foundation, consulte o System.Printing espaço para nome.
O exemplo de código a seguir demonstra o Document, UseAntiAlias, e Zoom propriedades das PrintPreviewControl. Para executar esse exemplo, coloque o código a seguir em um formulário e telefonar o InitializePrintPreviewControl método do construtor do formulário ou Load método de manipulação de eventos.
