You can print each page of a document using different page settings. To access the page settings, use the corresponding property of the QueryPageSettingsEventArgs. For more information about other properties of QueryPageSettingsEventArgs, see the QueryPageSettingsEventArgs Class MSDN topic.

You can also obtain the page number and page size for each page in a document using the PdfQueryPageSettingsEventArgs.PageNumber and PdfQueryPageSettingsEventArgs.PageSize properties, correspondingly.


The code snippet below handles the QueryPageSettings and PrintPage events to specify the landscape orientation for a second page and add an image on each printed page.

using DevExpress.Pdf;
using System.Drawing;

// Create a PDF Document Processor instance and load a PDF file
using (PdfDocumentProcessor documentProcessor = new PdfDocumentProcessor()) {

    // Declare PDF printer settings.
    PdfPrinterSettings settings = new PdfPrinterSettings();

    // Specify the page numbers to be printed.
    settings.PageNumbers = new int[] { 1, 2, 3, 4, 5, 6 };

    // Handle the PrintPage event to specify print output.
    documentProcessor.PrintPage += OnPrintPage;

    // Handle the QueryPageSettings event to customize settings for a page to be printed.
    documentProcessor.QueryPageSettings += OnQueryPageSettings;

    // Print the document using the specified printer settings.

    // Unsubscribe from PrintPage and QueryPageSettings events. 
    documentProcessor.PrintPage -= OnPrintPage;
    documentProcessor.QueryPageSettings -= OnQueryPageSettings;

private static void OnQueryPageSettings(object sender, PdfQueryPageSettingsEventArgs e) {

    // Print the second page in landscape size.
    if (e.PageNumber == 2) {
        e.PageSettings.Landscape = true;
    else e.PageSettings.Landscape = false;

// Specify what happens when the PrintPage event is raised.
private static void OnPrintPage(object sender, PdfPrintPageEventArgs e) {

    // Draw a picture on each printed page.
    using (Bitmap image = new Bitmap(@"..\..\DevExpress.png"))
        e.Graphics.DrawImage(image, new RectangleF(10, 30, image.Width / 2, image.Height / 2));
