En el siguiente ejemplo se supone que se ha creado un Button en un Form. El método printButton_Click del ejemplo crea una instancia de la clase PrintDocument, llama al método pd_PrintPage e imprime el archivo .bmp especificado en el método pd_PrintPage. Para ejecutar este ejemplo, hay que modificar la ruta de acceso al mapa de bits que se desea imprimir.
Se utilizan los espacios de nombres System.ComponentModel, System.Collections, System.Drawing, System.Drawing.Printing, System.Resources y System.Windows.Forms para este ejemplo.
