This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind.
In order to print the file, some application needs to open it...it may be yours, it may be a PDF reader. But something has to, or it can't get at the data to format it. What are you trying to achieve?

I have a try but I must load the document in the Form to have the contents and then print. Maybe you need C# PDF Viewer Components to realize.

I used iTextSharp for this, other codes where from others

C#

private void CombineMultiplePDFs(string[] sourceDir, string targetPath)
        
        {
            try
            {
                // step 1: creation of a document-object
                Document document = new Document();
                // step 2: we create a writer that listens to the document
                PdfCopy writer = new PdfCopy(document, new FileStream(targetPath, FileMode.Create));
                if (writer == null)
                {
                    return;
                }
                // step 3: we open the document
                document.Open();
                foreach (string fileName in sourceDir)
                {
                    //first we validate if pdf file is valid
                         
                    string extension = Path.GetExtension(fileName);
                    if (extension == ".pdf")
                    {
                        if (IsValidPdf(fileName) != true)
                        {
                            
                        }
                        else
                        {
                            // we create a reader for a certain document
                            //PdfReader.unethicalreading = true;
                            //unlockPdf(fileName);
                            PdfReader reader = new PdfReader(fileName);
                            rtbMessage.Text += "\n" + Path.GetFileName(fileName) + "  -   Added!";
                            PdfReader.unethicalreading = true;
                            
                            reader.ConsolidateNamedDestinations();
                            // step 4: we add content
                            for (int i = 1; i <= reader.NumberOfPages; i++)
                            {
                                PdfImportedPage page = writer.GetImportedPage(reader, i);

                    }
                }

The following code will search for all files in a give directory, use a method call PrintPDFs to automatically send the file to the default printer on the machine that this code is run on.

It will use adobe's ability to silently print a PDF, it will still open the files but i've also included code called FindAndKillProcess which will close adobe.

Without spending tons for a more sophisticated component this is going to be...probably at least...one of the easier options you'll have.

If you look at itextsharp or pdfsharp there are options to print the PDF that way which is the way i ended up going but the code below should work.

C#

string[] files = Directory.GetFiles(sourceFolder);
foreach (string file in files)
{
    PrintPDFs(file);
}

public static Boolean PrintPDFs(string pdfFileName)
{
    try
    {
        Process proc = new Process();
        proc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
        proc.StartInfo.Verb = "print";

        //Get application path will get default application for given file type ("pdf")
        //This will allow you to not care if its adobe reader 10 or adobe acrobat.
        proc.StartInfo.FileName = IOUtils.GetApplicationPath(pdfFileName, "pdf");
        proc.StartInfo.Arguments = String.Format(@"/p /h {0}", pdfFileName);
        proc.StartInfo.UseShellExecute = false;
        proc.StartInfo.CreateNoWindow = true;

        proc.Start();
        proc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
        if (proc.HasExited == false)
        {
            proc.WaitForExit(10000);
        }

        proc.EnableRaisingEvents = true;

        proc.Close();
        FindAndKillProcess("AcroRd32");
        return true;
    }
    catch
    {
        return false;
    }
}


public static bool FindAndKillProcess(string name)
{
    foreach (Process clsProcess in Process.GetProcesses())
    {
        if (clsProcess.ProcessName.StartsWith(name))
        {
            clsProcess.Kill();
            return true;
        }
    }
    return false;
}
