Order Printer - Display detailed taxes in payment details section

Hi,

I would like to change way the taxes are displayed in the default invoice template.

I would like to show the total of QST and the total of GST on separate lines in the payment details section, instead of showing it for each item.

Right now, it shows up for each item, but I would like to have at the bottom of the invoice :

Subtotal: $123,45

Shipping: $123,45

QST: $123,45

GST: $123,45

Total: $123,45

Is that possible?

Thank you
