If you previously enabled the printing of merchant transaction receipts and you no longer want or need them, you can quickly disable the function.
From the main screen, touch the Menu button.
Enter the merchant password and touch Confirm.
In the Configure application section, touch Printer options.
In the Copies section, slide the Merchant Copy Printouts toggle switch to the left.
If you have more than one terminal, repeat steps 1 to 4 for each additional terminal where you want to disable the printing of the merchant copy of the transaction receipts.
