Hello,

I am stuck into print pdf file directly to printer. I am using below code for print. It print but open pdf also.

See the code below:

ProcessStartInfo info = new ProcessStartInfo(filePath);

info.Verb = "Print";

info.CreateNoWindow = true;

info.WindowStyle = ProcessWindowStyle.Hidden;

Process.Start(info);

Accepted answer

string filePath = ""; // Give File Path ex(@"C:\PDF\", "*.pdf", SearchOption.AllDirectories)
ProcessStartInfo info = new ProcessStartInfo(filePath);

or Use Give Code below:

ProcessStartInfo info = new ProcessStartInfo(txtFileName.Text.Trim());
info.Verb = "Print";
info.CreateNoWindow = true;
info.WindowStyle = ProcessWindowStyle.Hidden;
Process.Start(info);

Worked excellent for me.

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();
