E-filing acknowledgement & submit hard copy of return

filed return can be printed by going to aces website by seaching the ret> filed and take print out, status filed is shown in print out, means its already submitted.

There is no such rule to submit hard copy to department, however if you feel that some mistakes may be there which needs to be corrected in future / revision of return, then submitting hard copy will save you with  forthcoming troubles as the same is submitted in hard copy to department, 

if you feel to submit the hard copy then obtain a dated acknowledgement from the officer with seal and sign.
