Here i'm going to explain how to print PDF File on Network Printer using c# .

you can develop windows as well as Console Application to test printing.

Step 1

Print PDF File using Adobe Reader.

Download and install adobe reader in which system your application will execute and give complete path while printing as-

C:\Program Files (x86)\Adobe\Reader 9.0\Reader\AcroRd32.exe

We write code as -

Code 1.1

string FilePath = @"E:\abc.pdf";
PrinterProcessName = "TEC B-EV4 (203 dpi)";                                        
string pdfArguments = string.Format("/n /s /o /h /p /t " + "\"" + FilePath + "\" " + "\"" + PrinterProcessName + "\"");
string pdfPrinterLocation = @"C:\Program Files (x86)\Adobe\Reader 9.0\Reader\AcroRd32.exe";               
ProcessStartInfo newProcess = new ProcessStartInfo(pdfPrinterLocation, pdfArguments);
newProcess.CreateNoWindow = true;
newProcess.RedirectStandardOutput = true;
newProcess.UseShellExecute = false;
Process pdfProcess = new Process();
pdfProcess.StartInfo = newProcess;
pdfProcess.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
pdfProcess.Start();
Thread.Sleep(1000);                    
System.GC.Collect();
System.GC.WaitForPendingFinalizers();

Code 1.2

string PathToExecutable = @"C:\Program Files (x86)\Adobe\Reader 10.0\Reader\AcroRd32.exe";
var PrintFileToPrinter = string.Format("/t \"{0}\" \"{1}\"", txtfilepath.Text, txtPrinterName.Text);
var args = string.Format("{0}", PrintFileToPrinter);
Process process = new Process();
process.StartInfo.FileName = PathToExecutable;
process.StartInfo.Arguments = args;
process.StartInfo.CreateNoWindow = true;
process.StartInfo.ErrorDialog = false;
process.StartInfo.UseShellExecute = false;
process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
process.Start();
 

Code 1.3

Process proc = new Process();
proc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
proc.StartInfo.Verb = "print";
proc.StartInfo.FileName =@"C:\Program Files (x86)\Adobe\Reader 10.0\Reader\AcroRd32.exe";
//proc.StartInfo.Arguments = String.Format(@"/p /h {0}", filepath);
proc.StartInfo.Arguments = String.Format("/p /h \"{0}\" \"{1}\"", filepath, txtPrinterName.Text);
proc.StartInfo.UseShellExecute = false;
proc.StartInfo.CreateNoWindow = true;
proc.Start();
proc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
if (proc.HasExited == false)
{
    proc.WaitForExit(1000);
}
 proc.EnableRaisingEvents = true;
 proc.Close();
 KillAdobe("AcroRd32");

private static bool KillAdobe(string name)
{
    foreach (Process clsProcess in Process.GetProcesses().Where(clsProcess => clsProcess.ProcessName.StartsWith(name)))
    {
         clsProcess.Kill();
         return true;
    }
return false;
}

 

Step 2

without Adobe reader

must set default printer in which printer you want to print.

Code 2.1

Process p = new Process();
p.StartInfo = new ProcessStartInfo()
{
     CreateNoWindow = true,
     Verb = "print",
     FileName = @"D:\QRCodeImages\Print.pdf",
};
p.Start();
Thread.Sleep(1000);
System.GC.Collect();
System.GC.WaitForPendingFinalizers();

Code 2.2

public  void printPDF()
{
   try
   {
        dynamic printernamewe = txtPrinterName.Text;
        PrinterClass.SetDefaultPrinter(printernamewe);
        dynamic printerName = printernamewe;                
        string pdfFileName = @"D:\QRCodeImages\Print.pdf";
        ProcessStartInfo psInfo = new ProcessStartInfo();
        psInfo.Verb = "Print"; // or "PrintTo"
        psInfo.FileName = pdfFileName;
        psInfo.Arguments = String.Format("/p /h \"{0}\" \"{1}\"", pdfFileName, printerName);
        psInfo.WindowStyle = ProcessWindowStyle.Hidden;
        psInfo.CreateNoWindow = true;
        psInfo.UseShellExecute = true;
        Process process = Process.Start(psInfo);  
    }
    catch (Exception ex)
    {
        Console.WriteLine(ex.Message);
    }
}

public static class PrinterClass
{
     [DllImport("winspool.drv", CharSet = CharSet.Auto, SetLastError = true)]
     public static extern bool SetDefaultPrinter(string Printer);
}
