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