awk '{sum += $1} END{print sum}' filename

but i'm not sure how to print rest of the columns, it gives the output of only first column

Use a for loop with array to sum each column:
awk '
        for ( i = 1; i <= NF; i++ )
                A[i] += $i
        for ( i = 1; i <= NF; i++ )
                printf "%d ", A[i]

        printf "\n"
} ' file

NB in a 32-bit awk printf can print large values only with %.f instead of %d.
