Invoice unit price display

Hello,

At the moment I,m configuring the invoice in the backend so I can print them on my businesspaper. Everything works fine, but there's one thing I just can't manage to change. In the normal invoice the product price is shown without tax. I want the price to be shown with tax.
In the backend the folowing code is showing this part.
<?php echo $currencyHelper ->format($item->order_product_price,$data->order_currency_id); ?>
Which code do I have to insert (at the bold text) to get the unit price with tax?
