Sometimes, you don't want to show the amount discounted on receipts. This might be because you have a wholesale register.
Important: This only applies to discounts on individual products. Discounting the entire sale using the discount button will always show on the receipt.
Simply navigate to your Setup tab and select "Outlets And Registers". From here you can select the register on which you want change settings by clicking "Edit".
Inside the edit page there is a small radio button that will allow you to toggle the receipt discounts on or off depending on your preference.
Then just click "Save" to save your changes and you're good to go!
