Kitchen Print Order applied to CATEGORY will be inherited to menu items under the CATEGORY
As an example, let's assign Dessert to 20, Appetizer to 1 and nothing for Lunch Sandwich
Let's ring up dessert item first and appetizer last.
On the kitchen ticket, Appetizer will be stacked on top. In this case, Lunch Sandwich will be last because it wasn't assigned any order.
