Question

I am currently working on asp.net c# Project on POS (Point Of Sale). I am using JavaScript function on page load but it populate print dialogue box in google chrome. This is my page load JavaScript function.

<script type="text/javascript">
        window.onload = function () {`enter code here`
            window.print();

        }

</script>

You may have alternate way .

• Save items in database, which you wants to print.
