I need to print a receipt for a school project I'm working on. I'm trying to print the page which contains this receipt by using window.print(). Only when I press the print button it doesn't print anything and just gives me a blank PDF
<div id='bon_overzicht'>
<table id='bon'>
<thead>
<tr>
<th>Product</th>
<th>Aantal</th>
<th>Prijs p/s</th>
<th>Totaal</th>
</tr>
</thead>
<tbody> <tr>

</tr>
</tbody>
</table>
</div>
How do I make sure this DIV gets printed? Any help would be appreciated.
