Thank you @nilpatel42 i use your code its look


but machine not read it
see AT/Pune/03-2022/17 its large size exactly that size of barcode line i want so
then machine will read it properly

For that you need reduce barcode length by reducing Value or
you can use bigger size sticker, so you can print long barcode properly

try with only ATCPune17, then try to scan it

Ok i will try on bigger size sticker and let you know
