TMS320F280039C: Can all printf be removed in ECDSA384?

Part Number: TMS320F280039C

Dear Champs,

I am asking this for our customer.

The user find there are several prints in the codes.

Like 

/* Custom logic */
if ((err = mp_read_radix(key->k, private_key, 16)) != CRYPT_OK){
printf("Updating private key failed.\n");
goto errkey;
}

Because "printf" takes up code size, can the user remove them all?

Or is there any consideration?
