Dear Friend,It is very easy to generate barcode with the help of c# programming language. In order to generate the barcode you have to do some steps:- Step1:- First you will have to create the prn file with the help of barcode printer Step2:- Write the code to replace the dynamic content. Step3:- Use Rowdataprinter .dll file to send command from computer to barcode printer. Thanks: If you need more help please command on the post i will explain you with the help of source code.

Hi Pravin, To generate barcode, a barcode font can simply do the job for you. As for printing barcode, I'm having a QR code lable printing APP for myself, which is easy-to-use and WYSIWYG. You can google lable printing APP according to what type of barcode you are going to generate. Hope this helps. Best, Makaveil

As for how to print barcode in c#.net on labels, i've ever tried a barcode tool from pqScan. And you can read barcode in c#.net

Nicholas Borrett · Answer

You mentioned 3 things in your question, which are generating the barcode, printing on labels, and scanning the barcodes. There is a .NET SDK named leadtools that can help you generate barcodes as images and print them on a Windows printer, and it also has barcode reading features.
