Exemplos
O exemplo de código a seguir Button supõe printButton que um nome e um PrintDocument nomeado pd tenham sido criados em um Form .The following code example assumes a Button named printButton and a PrintDocument named pd have been created on a Form. Verifique se o Click evento para o Button está associado ao printButton_Click método e se o PrintPage evento do PrintDocument está associado ao pd_PrintPage método no exemplo.Make sure the Click event for the Button is associated with the printButton_Click method and the PrintPage event of the PrintDocument is associated with the pd_PrintPage method in the example. O printButton_Click método do exemplo chama o Print método que gera o PrintPage evento e imprime o arquivo. bmp especificado no pd_PrintPage método.The printButton_Click method from the example calls the Print method raising the PrintPage event, and prints the .bmp file specified in the pd_PrintPage method. Para executar este exemplo, altere o caminho para o bitmap que você deseja imprimir.To run this example, change the path to the bitmap you want to print.
Use os System.Drawing System.Drawing.Printing namespaces,, e System.Windows.Forms para este exemplo.Use the System.Drawing, System.Drawing.Printing, and System.Windows.Forms namespaces for this example.
