What I have tried:

Timer myTimer=new Timer();
        private void Form1_Load(object sender, EventArgs e)
            myTimer.Tick+=new EventHandler(myTimer_Tick);
        private void myTimer_Tick(object sender, EventArgs e)
            string[] files = Directory.GetFiles(@"C:\PrintingDocument\");

            foreach (string file in files)
                //if (string.IsNullOrEmpty(file))
                //    //txtFileName.BackColor = Color.Yellow;
                //    //MessageBox.Show("Please Select file.");
                //    return;
                if (File.Exists(file))
                    Process proc = new Process();
                    proc.StartInfo.FileName = file;
                    proc.StartInfo.Verb = "Print";
                    proc.StartInfo.CreateNoWindow = true;
                    proc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
                    int exitcode = proc.ExitCode;
                    string fileName = Path.GetFileName(file);
                    System.IO.File.Move(file, @"C:\PrintedDocument\" + fileName);// Error: The process cannot access the file because it is being used by another process.
                    MessageBox.Show("Printed Successfully" + " " + DateTime.Now.ToString());

                    MessageBox.Show("Not File found" + " " + DateTime.Now.ToString());

Your Process will exit when it has started the Print task - that doesn't mean that the print operation is complete, that's down to the actual code that "print" uses to transfer the file to the printer.

Since the Windows print command only transfers text files, why not do the print yourself via a PrintDocument class instance instead, and gain a whole load of control over exactly what and how it is printed?
PrintDocument Class (System.Drawing.Printing)[^] The link includes a basic example.

Good answer - there's even sample code.

I don't want to use any click event i want to use only timer basis.
like, when i tried but its getting error.
OriginalGriff 9-Nov-16 6:12am
Why would you have to use a "click event" - that's sample code to show the class, not Microsoft telling you exactly how you should write your application...

My document successfully print but my file was not moving in another folder.
OriginalGriff 9-Nov-16 6:42am
Yes, I know.
That's because it was in use while it is printing...
Agarwal1984 9-Nov-16 6:47am
I have debugged my code and i have written WaitForExit, WaitForExit was calling after printing command run.
and then i am closing process also.
OriginalGriff 9-Nov-16 6:57am
Just because the process you spawned is complete, doesn't mean that it hasn't spawned more processes of it's own to actually do the print operation. And if they are holding the file until the paper comes out of the printer for example, then the file is in use until that time.
You are much better off not relying on external processes, but handling the file print yourself. That way, you know when the file is in use, and exactly when it's finished with...
Agarwal1984 9-Nov-16 7:01am
So, what can i do for that, because i will be run application on server end without any UI or Button click event.
It will be run automatically. On client computer request.
OriginalGriff 9-Nov-16 7:33am
Why do you assume that if an example shows a click event handler that's the only thing you can use it with?
When you watch a car ad on TV, and it shows people driving around Mumbai as if there was no traffic just for the fun of it, do you assume you can't drive that car in a small town? Or on a motorway? Or the School run?

I have tried windows service also for that functionality but Process did not run in windows service.
File was moving through windows service but not printing.
OriginalGriff 9-Nov-16 8:18am
So. Don't. Use. A. Process.
Agarwal1984 9-Nov-16 23:24pm
so, what can we use in window service?
