you need not send hard copy. In case of difficulty in e verification. Do not bother yourself. Take a print out of ITR V  , sign it and send it by ordinary post to CPC Bangalore. As of now, e verification is introduced only to get rid of ITR V sending at your end  and data entry of receipt of ITR V at CPC end.
