One of the best approaches (in my opinion) to print document files (including PDF DOC DOCX etc.) without loading it first using its native viewer is to load it as image (rasterize the document file) and then print it as regular WPF ImageSource object. However since the PDF format is not natively supported by .NET or WPF classes you will need to use a programming library (like LEADTOOLS) that supports rasterizing PDF documents. The following code shows how you can load the PDF file as image (rasterize it) using LEADTOOLS and then convert it to WPF ImageSource object and print it without showing any UI to the user: using System.Printing; //... //... private void buttonPrintPDF_Click( object sender RoutedEventArgs e) { using (Leadtools.Codecs.RasterCodecs _codecs = new Leadtools.Codecs.RasterCodecs()) { //Load the PDF file as RasterImage object using (Leadtools.RasterImage _image = _codecs.Load(@ c:\Users\Public\Documents\LEADTOOLS Images\Leadtools.pdf )) { // Convert the RasterImage object to WPF ImageSource System.Windows.Media.ImageSource myPDFImage = Leadtools.Windows.Media.RasterImageConverter.ConvertToSource(_image Leadtools.Windows.Media.ConvertToSourceOptions.None); //Render the ImageSource var vis = new DrawingVisual(); var dc = vis.RenderOpen(); dc.DrawImage(myPDFImage new Rect { Width = myPDFImage.Width Height = myPDFImage.Height }); dc.Close(); //Prepare the ImageSource for printing var pdialog = new PrintDialog(); //Set the printer name pdialog.PrintQueue = new PrintQueue( new PrintServer() Microsoft XPS Document Writer ); // this will be your printer. any of these: new PrintServer().GetPrintQueues() pdialog.PrintTicket.CopyCount = 3; // number of copies pdialog.PrintTicket.PageOrientation = PageOrientation.Landscape; //Print the Image pdialog.PrintVisual(vis canvas ); } } }

You could try Spire.PDF for WPF to print PDF documents without opening it or invoking PrintDialog PdfDocument doc = new PdfDocument(); doc.LoadFromFile(sample.pdf); doc.PrintDocument.Print();
