Hm, more like:

public String toPrint() {
    StringWriter stringWriter = new StringWriter();
    PrintWriter printWriter = new PrintWriter(stringWriter);

    toPrint(printWriter);

    return stringWriter.toString();
}

because:
	1) You cannot pass a StringBuffer to PrinterWriter's contructor
	2) StringBuffer doesn't have a getBuffer() method
	3) StringWriter has a toString() method
	4) You can't return a String from a method that declares its return
	   type as 'void' obviously

Either way perhaps it is safer in cases like this to point to existing code
(that is known to compile, etc) as an example on how to use specific
constructs?
