It depends.
Sometime you will receive your boarding pass for the two flights directly at departure, sometime you need to get your boarding pass on transfer desk: on departure they tell you about it, this is mostly due to too many hours before the second flight. Transfer desk on airside will provide you the ticket, but they will handle the baggage. Transfer desk on other side: Just ask to be sure if the baggage will follow you or if you need to get them and re-check.
On seldom case you need to do a new check-in (on check-in area). In this case having the baggage receipt will help them to control that the right baggage are on the system. It happened to me few times on "transferred flight (missed flights)". No need to get the baggage, they just need the receipt to be sure about moving the correct baggage. But I think you will be probably on one of the first two categories (but in case of missed connection).
