It is likely that you are seeing the shell's built in "printf" instead 
of coreutils' printf.

Test with the following:

    $ type printf
    printf is a shell builtin

Then compare:

    $ printf --version
    bash: printf: --: invalid option
    printf: usage: printf [-v var] format [arguments]

    $ env printf --version | head -n1
    printf (GNU coreutils) 8.23.170-02f67

To use the non built-in printf, use 'env' (or specify a full path such 
as /usr/bin/printf, though that is less portable).

regards,
 - assaf
