How to scan numeric and alpha-bate values in Barcode Laravel 5.4

I have used Milon package to generate Barcode in Laravel 5.4 but I am unable to scan barcode while I use barcode value as ETOR11113905 . The code which I have used to generate barcode is below.

DNS1D::getBarcodePNG('ETOR11113905', 'C39E');

Please guide me towards the right path.
