Crystal report does not accept user's printer settings

Question

I'm a C# developer and I need to use Crystal Report for my editions.

The problem is that it only prints in portrait. When I try to change the print settings, they are ignored. If, for example, I choose "landscape" in the printer settings, it will still print in portrait.

I've found a lot of topics about this but no working answer. In particular, I saw that you could uncheck "optimized for display", but that doesn't change anything.

I tried to cheat by creating a "print" button and coding it myself to force the parameters:

private void OnPrintButtonClick(object sender, RoutedEventArgs e)
{
    PrintDialog PrintD = new PrintDialog();
    Nullable<Boolean> print = false;
    try
    {
        print = PrintD.ShowDialog();
    }
    catch (Exception exc)
    {
        MessageBox.Show("Imprimante non trouvée: " + exc.Message, "Erreur");
    }

    if (print == true)
    {
        PrintQueue printQueue = PrintD.PrintQueue;
        report.PrintOptions.PrinterName = printQueue.FullName;
        Debug.WriteLine("Printer Name: " + printQueue.FullName);
        System.Drawing.Printing.PrinterSettings printerSettings = new System.Drawing.Printing.PrinterSettings();
        printerSettings.PrinterName = printQueue.FullName;
        report.PrintToPrinter(1, false, 0, 0);
    }
}

It works on most printers, but today I have a problem with a client where printing causes a "System.Runtime.InteropServices.COMException: invalid printer name" error.

The ideal would be for the application to work "natively" with the settings the user chooses, without having to force anything, I guess.

I'm on CR 13.0.22 and I've run out of ideas.

I assume that you can get Page Orientation from print dialog with PrintD.PrintTicket.PageOrientation.

How about setting this value to report.PrintOptions.PaperOrientation before calling PrintToPrinter function.

Here is a code example below that you might try.

if (print == true)
{
    PrintQueue printQueue = PrintD.PrintQueue;
    report.PrintOptions.PrinterName = printQueue.FullName;
    System.Drawing.Printing.PrinterSettings printerSettings = new System.Drawing.Printing.PrinterSettings();
    printerSettings.PrinterName = printQueue.FullName;

    var orientation = PrintD.PrintTicket.PageOrientation;

    if (orientation == PageOrientation.Landscape)
    {
        report.PrintOptions.PaperOrientation = CrystalDecisions.Shared.PaperOrientation.Landscape;
    }

    if (orientation == PageOrientation.Portrait)
    {
        report.PrintOptions.PaperOrientation = CrystalDecisions.Shared.PaperOrientation.Portrait;
    }

    report.PrintToPrinter(1, false, 0, 0);
}
