If you wish to print out a receipt, there are two options to perform this.

Firstly, if the Till Order is ready to be officially Despatched, you can click on the 'Despatch Item' which progresses the Order and also prints out a Receipt automatically.

Secondly, if the Till Order is not ready to be officially Despatched, you can click on 'Print' which will keep the Order in the current status and print out a copy of the Receipt.
