Duplex Mode print not work

aspose.png (27.2 KB)

Hi !
I have been struggling for a few days to print on both sides with the Aspose.PDF module.
I tried all the known variants and I can’t understand where I’m wrong.

I used other printing components that are functional, but Aspose.PDF does not want …

Can you help me ?

    public void PrintingPDFHidePrintDialog(string vs_file)
        // Create PdfViewer object
        PdfViewer viewer = new PdfViewer();

        // Open input PDF file

        // Set attributes for printing
        viewer.AutoResize = true;         // Print the file with adjusted size
        viewer.AutoRotate = true;         // Print the file with adjusted rotation

        viewer.PrintPageDialog = false;   // Do not produce the page number dialog when printing

        // Create objects for printer and page settings and PrintDocument
        System.Drawing.Printing.PrinterSettings ps = new System.Drawing.Printing.PrinterSettings();
        System.Drawing.Printing.PageSettings pgs = new System.Drawing.Printing.PageSettings();

        ps.FromPage = 1;
        ps.ToPage = 3;
        ps.PrintRange = PrintRange.SomePages;
        // Set XPS/PDF printer name
        ps.PrinterName = cbx_imprimanta.Text;

        // Set PageSize (if required)
        pgs.PaperSize = new System.Drawing.Printing.PaperSize("A4", 827, 1169);

        // Set PageMargins (if required)
        pgs.Margins = new System.Drawing.Printing.Margins(0, 0, 0, 0);

        if (ps.CanDuplex)
            ps.Duplex = Duplex.Vertical;
            MessageBox.Show("No Duplex.Mode");

        // Print document using printer and page settings
        viewer.PrintDocumentWithSettings(pgs, ps);

        // Close the PDF file after priting

Hi !
I am using the latest version 22.3, as the work project has 3 days, and I installed the components from Nuget.
