Unpopular (?) opinion: The cashdrawer should open before the receipt has finished printing to speed up the exchange of money... That way, the cashier can already make change, etc...

But I do also see that making sure the receipt printed first before allowing cash-transactions could make sense/might be prefered...

Alternative: Add drawerBefore in addition and add (yet another) option to pretixPOS to chose the one or the other...
