Print Pdf File in C# - Print PDF File to Default Printer using Printer and Page Settings

This article describes how to Print PDF File to Default Printer using Printer and Page Settings in C#.

The PdfViewer class allows you to print a PDF file to the default printer. You need to create a PdfViewer object and open the PDF using the BindPdf method. To specify different print settings, use the PageSettings and PrinterSettings classes. Finally, call the PrintDocumentWithSettings method to print the PDF to the default printer. The following code snippet shows how to print PDF to the default printer with printer and page settings.

.NET Core 3.1

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET

private static void SimplePrint()
{
    // The path to the documents directory
    string dataDir = RunExamples.GetDataDir_AsposePdfFacades_Printing();

    // Create PdfViewer object
    using (var viewer = new Aspose.Pdf.Facades.PdfViewer())
    {
        // Open input PDF file
        viewer.BindPdf(dataDir + "PrintDocument.pdf");

        // 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
        var ps = new Aspose.Pdf.Printing.PrinterSettings();
        var pgs = new Aspose.Pdf.Printing.PageSettings();
        var prtdoc = new System.Drawing.Printing.PrintDocument();

        // Set printer name
        ps.PrinterName = prtdoc.PrinterSettings.PrinterName;

        // Set PageSize (if required)
        pgs.PaperSize = Aspose.Pdf.Printing.PaperSizes.A4;

        // Set PageMargins (if required)
        pgs.Margins = new Aspose.Pdf.Devices.Margins(0, 0, 0, 0);

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

.NET 8

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET

private static void SimplePrint()
{
    // The path to the documents directory
    string dataDir = RunExamples.GetDataDir_AsposePdfFacades_Printing();

    // Create PdfViewer object
    using var viewer = new Aspose.Pdf.Facades.PdfViewer();

    // Open input PDF file
    viewer.BindPdf(dataDir + "PrintDocument.pdf");

    // 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
    var ps = new Aspose.Pdf.Printing.PrinterSettings();
    var pgs = new Aspose.Pdf.Printing.PageSettings();
    var prtdoc = new System.Drawing.Printing.PrintDocument();

    // Set printer name
    ps.PrinterName = prtdoc.PrinterSettings.PrinterName;

    // Set PageSize (if required)
    pgs.PaperSize = Aspose.Pdf.Printing.PaperSizes.A4;

    // Set PageMargins (if required)
    pgs.Margins = new Aspose.Pdf.Devices.Margins(0, 0, 0, 0);

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

In order to display a print dialog, try using the following code snippet:

.NET Core 3.1

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET

private static void PrintWithPrintDialog()
{
    // The path to the documents directory
    string dataDir = RunExamples.GetDataDir_AsposePdfFacades_Printing();

    // Create PdfViewer object
    using (var viewer = new Aspose.Pdf.Facades.PdfViewer())
    {
        // Open input PDF file
        viewer.BindPdf(dataDir + "PrintDocument.pdf");

        // 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

        var printDialog = new System.Windows.Forms.PrintDialog();
        if (printDialog.ShowDialog() == DialogResult.OK)
        {
            // Document printing code goes here

            // Convert PrinterSettings and PageSettings to Aspose.PDF counterparts via extension methods
            // provided in the Aspose.Pdf.Printing namespace
            Aspose.Pdf.Printing.PrinterSettings ps = printDialog.PrinterSettings.ToAsposePrinterSettings();
            Aspose.Pdf.Printing.PageSettings pgs = printDialog.PrinterSettings.DefaultPageSettings.ToAsposePageSettings();

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

.NET 8

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET

private static void PrintWithPrintDialog()
{
    // The path to the documents directory
    string dataDir = RunExamples.GetDataDir_AsposePdfFacades_Printing();

    // Create PdfViewer object
    using var viewer = new Aspose.Pdf.Facades.PdfViewer();

    // Open input PDF file
    viewer.BindPdf(dataDir + "PrintDocument.pdf");

    // 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

    var printDialog = new System.Windows.Forms.PrintDialog();
    if (printDialog.ShowDialog() == DialogResult.OK)
    {
        // Document printing code goes here

        // Convert PrinterSettings and PageSettings to Aspose.PDF counterparts via extension methods
        // provided in the Aspose.Pdf.Printing namespace
        Aspose.Pdf.Printing.PrinterSettings ps = printDialog.PrinterSettings.ToAsposePrinterSettings();
        Aspose.Pdf.Printing.PageSettings pgs = printDialog.PrinterSettings.DefaultPageSettings.ToAsposePageSettings();

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

Choosing paper source by PDF page size

Since the 24.4 release, choosing paper source by PDF page size in the print dialog is possible. The next code snippet enables picking a printer tray based on the PDF’s page size.

This preference can be switched on and off using the Document.PickTrayByPdfSize property.

.NET Core 3.1

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET

private static void PickTrayByPdfSize()
{
    // The path to the documents directory
    string dataDir = RunExamples.GetDataDir_AsposePdfFacades_Printing();

    // Create a new document
    using (var document = new Aspose.Pdf.Document())
    {
        // Add a new page and some content
        var page = document.Pages.Add();
        page.Paragraphs.Add(new Aspose.Pdf.Text.TextFragment("Hello world!"));

        // Set the flag to choose a paper tray using the PDF page size
        document.PickTrayByPdfSize = true;

        // Save the document
        document.Save(dataDir + "PickTrayByPdfSize_out.pdf");
    }
}

.NET 8

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET

private static void PickTrayByPdfSize()
{
    // The path to the documents directory
    string dataDir = RunExamples.GetDataDir_AsposePdfFacades_Printing();

    // Create a new document
    using var document = new Aspose.Pdf.Document();

    // Add a new page and some content
    var page = document.Pages.Add();
    page.Paragraphs.Add(new Aspose.Pdf.Text.TextFragment("Hello world!"));

    // Set the flag to choose a paper tray using the PDF page size
    document.PickTrayByPdfSize = true;

    // Save the document
    document.Save(dataDir + "PickTrayByPdfSize_out.pdf");
}
