Currently, if you place a POS order on hold (essentially, do not move it to shipped), and then you print an invoice off of it, the invoice amount will be the cart total of the POS order, but it will not have the tax amount.
In most instances, before a POS order is put into shipped, we do need the POS order invoice to display the complete amount due, which means, it should include the tax that will be due.
Expected result -> Printing an invoice on an unshipped POS order display the total price of the POS order AND tax.
Currently -> Printing an invoice on an unshipped POS order only displays the cart total price of the POS order and DOES NOT include the tax that would be due.
