I have read that many other members here successfully found a place in Delhi for fingerprinting, did you do some SEARCH on that topic?
It is best to download the form from the FBI website - print it in color, on heavy stock card or heavy bond paper.
You can do it yourself but it is better to be done by the agency or people who specialize in doing so, that way you don't waste time for mistake. I would strongly suggest not doing it by yourself. If you are unsure wheter your FP can be read correctly by FBI, you can send two application in two separate envelope and fee enclosed.
You don't or can't add set of FP to the same application, you need to send a fresh application with $18 fee each.
