JavaScript accessing variables declared in calling function

It's hard to explain my question, so I'm posting some code.

function caller(func) {
    function printMessage(message) {
        console.log(message);
    }

    func();
}

function callee() {
    printMessage('hello world');
}

caller(callee);

I want to access printMessage from callee, but as it currently stands, this throws a ReferenceError. I'd like to avoid declaring printMessage globally, if possible.
