You can use a barcode library such as LEADTOOLS to write (draw) the barcodes on an image at the server side using .NET code. (Disclaimer: I’m an employee of this library's vendor). The following code writes a barcode on an image and saves it into a MemoryStream: //Create white image RasterImage bitmapImage = RasterImage .Create(400 150 24 300 RasterColor .White); //Write the barcode on the image Leadtools.Barcode. BarcodeEngine engine = new BarcodeEngine (); BarcodeWriteOptions writeOptions = engine.Writer.GetDefaultOptions( BarcodeSymbology .Code3Of9); string sampleData = 123-45678 ; //There are many supported types not just Code 3 of 9 engine.Writer.WriteBarcode(bitmapImage new BarcodeData ( BarcodeSymbology .Code3Of9 sampleData) writeOptions); //Save the image to a stream RasterCodecs codecs = new RasterCodecs (); codecs.Save(bitmapImage memoryStream RasterImageFormat .Png 24); You can then return the resulting image as part of your response page (receipt) and invoke printing of the page using JavaScript. There's a free evaluation edition on www.leadtools.com with free technical support.
