Code Sample for PDF Print
The code below was taken from the PDF Print demo application available for download in the PDF Print product package. In this sample an instance of the PdfPrint class is constructed and used to silently print a selected PDF document.

private void btnPrintPdf_Click(object sender, EventArgs e)
{
    if (pdfFileTextBox.Text.Trim().Equals(String.Empty))
    {
        MessageBox.Show("Please choose a source PDF file", "Choose PDF file", MessageBoxButtons.OK);
        return;
    }

    // the source pdf file
    string pdfFileName = pdfFileTextBox.Text.Trim();

    // start page number
    int startPageNumber = int.Parse(textBoxStartPage.Text.Trim());
    // end page number
    // when it is 0 the conversion will continue up to the end of document
    int endPageNumber = 0;
    if (textBoxEndPage.Text.Trim() != String.Empty)
        endPageNumber = int.Parse(textBoxEndPage.Text.Trim());

    // create the PDF printer 
    PdfPrint pdfPrint = new PdfPrint();

    // set the license key
    pdfPrint.LicenseKey = "OrSltaGgtaW1o7ultaaku6Snu6ysrKy1pQ==";

    // set the document name
    pdfPrint.DocumentName = "PDF Silent Printing";

    // enable or disable color printing
    pdfPrint.DefaultPageSettings.Color = cbPrintColor.Checked;

    // set the PDF printing color and resolution
    pdfPrint.Color = GetSelectedPrintColor();
    pdfPrint.Resolution = int.Parse(textBoxResolution.Text);

    // select the printer
    string selectedPrinterName = GetSelectedPrinterName();
    if (selectedPrinterName != null)
        pdfPrint.PrinterSettings.PrinterName = selectedPrinterName;

    // set paper size
    PaperSize selectedPaperSize = GetSelectedPaperSize();
    if (selectedPaperSize != null)
        pdfPrint.DefaultPageSettings.PaperSize = selectedPaperSize;

    // set paper orientation
    pdfPrint.DefaultPageSettings.Landscape = GetSelectedPageOrientation() == "Landscape";

    // set paper margins 
    pdfPrint.DefaultPageSettings.Margins = new Margins((int)(float.Parse(leftMarginTextBox.Text) * 100),
        (int)(float.Parse(rightMarginTextBox.Text) * 100),
        (int)(float.Parse(topMarginTextBox.Text) * 100),
        (int)(float.Parse(bottomMarginTextBox.Text) * 100));

    // the demo output directory
    string outputDirectory = Path.Combine(Application.StartupPath, @"DemoFiles\Output");

    Cursor = Cursors.WaitCursor;

    try
    {
        pdfPrint.Print(pdfFileName, startPageNumber, endPageNumber);
    }
    catch (Exception ex)
    {
        // The conversion failed
        MessageBox.Show(String.Format("An error occurred. {0}", ex.Message), "Error");
        return;
    }
    finally
    {
        Cursor = Cursors.Arrow;
    }

    MessageBox.Show("Print Completed", "Print Completed", MessageBoxButtons.OK);
}
