You can write barcodes using toolkit like ZXing or leadtools. See these links: https://github.com/zxing/zxing http://www.codeproject.com/Articles/690035/Choosing-the-Right-Barcode-for-Your-Application To my knowledge, leadtools also supports writing PRN files, but I didn't try this myself.

Dear friend, It is very easy to generate .prn file. In order to generate .prn file you need to follow some steps. Step 1:- You will have to use barcode printer . step 2:- Change barcode printer port number to file which is used to generate file from the printer. step 3:- Design barcode with the help of bartender software. step 4:- Give print command to print the barcode step 5:- After clicking the print option you will have to assign the path where you want to store the prn file .

@ Murli Jadhav , I am sharing complete c# code. You can find how to replace text of .prn File. Find my attached file. string p = Application.StartupPath.ToString() + @"\SILICALARGE.FMT";// read your created .FMT file (Prn file) string str = ""; FileStream fs = new FileStream(p, FileMode.Open, FileAccess.Read); StreamReader r = new StreamReader(fs); r.BaseStream.Seek(0, SeekOrigin.Begin); str = r.ReadToEnd().ToString(); r.Close(); fs.Close(); //string barcode = "BHEL ED" + ">I" + txt6.Text + ">I" + txt7.Text + ">I" + txtVoc.Text + ">I" + txtISC.Text + ">I" + txt12.Text + ">I" + txt13.Text + ">I" + txt11.Text + ">I" + txt14.Text + ">I" + ">I"; string barcode = "1"; str = Microsoft.VisualBasic.Strings.Replace(str, " DESCRIPTION1 ", comboBox2.Text.Substring(0, comboBox2.Text.IndexOf('-') + 1), 1, -1, Microsoft.VisualBasic.CompareMethod.Text); str = Microsoft.VisualBasic.Strings.Replace(str, " DESCRIPTION2 ", comboBox2.Text.Substring(comboBox2.Text.IndexOf('-') + 1).Trim(), 1, -1, Microsoft.VisualBasic.CompareMethod.Text); str = Microsoft.VisualBasic.Strings.Replace(str, " DATE ", textBox2.Text.Trim(), 1, -1, Microsoft.VisualBasic.CompareMethod.Text); str = Microsoft.VisualBasic.Strings.Replace(str, " BARCODE ", textBox1.Text.Trim(), 1, -1, Microsoft.VisualBasic.CompareMethod.Text); string fn = @"D:\TempBat.txt"; FileInfo fl = new FileInfo(fn); if (fl.Exists == true) { fl.Delete(); } fs = new FileStream(fn, FileMode.OpenOrCreate, FileAccess.Write); StreamWriter w1 = new StreamWriter(fs); w1.WriteLine(str); w1.Close(); fs.Close(); String portName = "Barcode"; //-- RawDataPrinter.Printer RDP = new RawDataPrinter.Printer(); object ErrNum = 0; object ErrDesc = ""; string PrinterName = ""; PrinterName = "Barcode"; if (PrinterName == null) PrinterName = ""; RDP.PrintRawData("", fn, PrinterName, false, 0, 0, false, "", "", ref ErrNum, ref ErrDesc); //insert srl no in to database

Hello Muhammad nissam , Basically you want to say how to change the barcode data at the run time ?. if this is your question I am explaining again how you can change the barcode data. Step1:- Replace the data which you want to change at runtime with unique name Step2:- Read the .prn file and replace the unique value with run-time generated value Step3:- Last print the updated .prn file In case these steps are not sufficient for you, next time I will send you complete code
