Hi Hisanth,

Maybe you need a third party library to help you.

You could go to their website to download.

https://www.neodynamic.com/products/printing/thermal-label/sdk-vb-net-csharp/download/

Here they have already written  a project sample for you.

To learn more about the library , you could refer to

You could also refer to their articles about barcode.

If you  want to work in visual studio, you could also  download the library using nuget.

To use it in visual studio, you should change configuration of visual studio.

Please  go to    Tools->Options->Projects and Solutions->Web Products and click the Use the 64 bit version of IIS Express For web sites ... and restart visual studio

Best regards,

Keep in mind, you have zero control over where ASP.Net prints anything because the browser has no control. You can only open a print dialog from the browser and even then you can't tell it anything else about printing such as size, printer to print to, etc..
