   printf( "%s",[myString cString]);

or maybe lossyCString, as cString will raise an exception if some of
the characters aren't representable in the default cstring encoding
(usually MacOSRoman).

You can also use MPWFoundation's  MPWByteStream class, which for an
isolated case would look like this:

   [[MPWByteStream Stdout] writeObject:myString];

or

   [outStream writeObject:myString];

if you have already gotten the Stdout stream earlier.  The clue about
-writeObject: is that it will take any object whatsoever and print it
(to an arbitrary stream).  The default behavior is to print the
-description, but objects can easily override that behavior.
