Example

This example shows how to customize print output and change settings for a page to be printed.

A document is printed with the specified initial printer settings using the PdfDocumentProcessor.Print method. In this example, the page numbers that should be printed in a document are specified using the PdfPrinterSettings.PageNumbers property.

When a page is printed, page settings for this page are queried via the PdfDocumentProcessor.QueryPageSettings event.

In this example, the second page of a document is printed in landscape orientation by setting the PdfQueryPageSettingsEventArgs.PageSettings.Landscape property to true when the PdfDocumentProcessor.QueryPageSettings event is handled.

When the document is sent to a printer, the PdfDocumentProcessor.PrintPage event is raised.

To draw an additional image on a printed page, the Graphics property of the PdfPrintPageEventArgs is used when the PdfDocumentProcessor.PrintPage event is handled. This image is drawn on each page by calling the Graphics.DrawImage method.
