How to add "Print Bill" to left hand side bar in POS view?

I am going to refer you to a post where @QMcKay answered that very question.

I never print the bill automatically when the payment is processed. Instead, I created a button to print the bill manually, on-demand, whenever the need arises. So this is just an alternate setup that is helpful to have in many cases.
