This is still too many classes. Can we just pull out `println` to a method like:

private static void println(Object printer, Object o) {
    if (printer instanceof printStream ps) {
        ps.println(o);
    } else {
        ((PrintWriter) printer).println(o);
    }
}

Should be fewer classes to accomplish the same functionality.
