visitor visa interview rescheduling and fingerprinting

[americandesimd]

hello frnds,

Are all the documents required for fingerprinting which are needed for interview? what docs in particular are required for finger printing.
If I want to re schedule my in-laws's interview date, do I also need to reschedule the finger printing date? I did not see any option for finger printing.

Thanks.
