At the top of the Order List you will find the Auto / Manual Accept options and the Auto Print Options.
Orders will only auto print when they are accepted. So if you want them to truly auto print without any human interaction, you must select Auto Accept, and then click one of the receipts you want to auto print.
You can use any combination of these settings, for example:
a) If you want to manually accept orders first, then they print the combined receipt, select Manual Accept, and tick the combined receipt option. This will automatically print the order once you have accepted it.
b) If you want to manually accept orders, then print a separate food receipt and drink receipt, select Manual Accept, and tick the Drink Receipt and Food Receipt options. This will automatically print the two separate receipts once you have accepted the order.
c) If you want to auto accept orders and auto print a combined receipt, select Auto Accept and tick the Combined Receipt option. This will automatically accept and print the order with no human interaction.
