The BPs printed are not unique and they can be copied, PDF'd or even faxed and still work. You can have an electronic BP and a paper one and they will both work. I've done all of that.
When I check a bag I am routinely given another BP (and an additional drink coupon if flying BS). All of them seem valid.
