/**
 * Class Destination is a printing attribute class, a URI, that is used to
 * indicate an alternate destination for the spooled printer formatted
 * data. Many PrintServices will not support the notion of a destination
 * other than the printer device, and so will not support this attribute.
 * <p>
 * A common use for this attribute will be applications which want
 * to redirect output to a local disk file : eg."file:out.prn".
 * Note that proper construction of "file:" scheme URI instances should
 * be performed using the <code>toURI() method of class
 * {@link java.io.File File}.
 * See the documentation on that class for more information.
 * <p>
 * If a destination URI is specified in a PrintRequest and it is not
 * accessible for output by the PrintService, a PrintException will be thrown.
 * The PrintException may implement URIException to provide a more specific
 * cause.
 * <P>
 * <B>IPP Compatibility: Destination is not an IPP attribute.
 * <P>
