Printing discount amount/service charge below the total amount in the receipt

Change receipt formatting like below to print discount separately from the item list.

Note: If you are trying to add a service charge below the amount instead of a discount, then please replace the AdditionalDiscount (Mentioned in red font) to ServiceCharge, also replace Discount (Mentioned in red font) to Service Charge
