Possible to board and travel without e-ticket print out. One of prescribed id document is must. TTE will charge only Rs. 50/- as already replied by Mr. Jitesh.
@ Plz insist on payment of Rs. 50/- to TTE and insist on receipt for such payemnt. Without this, you may land in trouble while exiting out at your destination Railway Station. As you will not be having e-ticekt print out and not even Rs. 50/- receipt, the absence of which will invite trouble and hassles for you.
