Issuing of vouchers
In order to issue a voucher, the total sum of item lines in the box must be negative.
Here you will get a button in the bottom right corner, on the same line as "Total" where it says "Voucher".
Press on Voucher to issue the voucher, which is then added as a line item in the box.
Then you press Pay and select just one of the payment types, e.g. "Cash".
Please note that vouchers are first printed after the standard receipt has been printed.
