How can we set the settings for printing in the new print preview of windows 11?

Question

We are struggling with the new print preview with windows 11. Before the print we are changing some settings based on some configuration of our program. These settings are applied to the old print dialog of windows, but on the new one our settings are ignored.

I wrote a small example. I just want to have the orientation in Landscape (German: Querformat):

        private void PrintBt_Click(object sender, RoutedEventArgs e)
        {
            // Create the print dialog object and set options
            PrintDialog pDialog = new PrintDialog();
            pDialog.PrintTicket.PageOrientation = System.Printing.PageOrientation.Landscape;
            pDialog.PageRangeSelection = PageRangeSelection.AllPages;
            pDialog.UserPageRangeEnabled = true;
            // Display the dialog. This returns true if the user presses the Print button.
            Nullable<Boolean> print = pDialog.ShowDialog();            
        }

We tried with the .NET 6 and with .NET Framework 4.8 and in both cases it's not working.

Hi @Alessandro, Welcome to Microsoft Q&A.

Updated in WPF:

private void InvokePrint(object sender, RoutedEventArgs e)
{
    // Create the print dialog object and set options
    PrintDialog pDialog = new PrintDialog();
    PrintTicket printTicket = pDialog.PrintTicket;
    printTicket.PageOrientation = PageOrientation.Landscape; // Set the print orientation here
    pDialog.PageRangeSelection = PageRangeSelection.AllPages;
    pDialog.UserPageRangeEnabled = true;
    // Display the dialog. This returns true if the user presses the Print button.
    Nullable<Boolean> print = pDialog.ShowDialog();
    if (print == true)
    {
    }
}

Use PrintDialog in C# winform.

You can modify printer settings using PrinterSettings.

The following code modifies printerSettings.DefaultPageSettings directly. If you choose a printer other than the default, you may have to modify the code location. It can be directly placed inside if (printDialog1.ShowDialog() == DialogResult.OK).

private void button1_Click(object sender, EventArgs e)
{
    // Get the selected printer settings from the PrintDialog
    PrinterSettings printerSettings = printDialog1.PrinterSettings;
    // Set the default printer settings
    printerSettings.DefaultPageSettings.Landscape = true;
    // Create the PrintDialog object
    // Show the print dialog
    if (printDialog1.ShowDialog() == DialogResult.OK)
    {
        // Create the PrintDocument object
        PrintDocument printDocument = new PrintDocument();
        // Set the PrinterSettings for the PrintDocument
        printDocument.PrinterSettings = printerSettings;
        // Set the PrintPage event handler for the PrintDocument
        printDocument.PrintPage += PrintDocument_PrintPage;
        // Start the printing process
        printDocument.Print();
    }
}
private void PrintDocument_PrintPage(object sender, PrintPageEventArgs e)
{
    // Add your printing logic here
    // This event is triggered for each page that needs to be printed
}

Best Regards,
