/**
 * Class {@code Destination} is a printing attribute class, a {@code URI}, that
 * is used to indicate an alternate destination for the spooled printer
 * formatted data. Many {@code PrintServices} will not support the notion of a
 * destination other than the printer device, and so will not support this
 * attribute.
 * 
 * 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 {@code URI} instances should be performed
 * using the {@code toURI()} method of class {@link File File}. See the
 * documentation on that class for more information.
 * 

 * If a destination {@code URI} is specified in a PrintRequest and it is not
 * accessible for output by the {@code PrintService}, a {@code PrintException}
 * will be thrown. The {@code PrintException} may implement {@code URIException}
 * to provide a more specific cause.
 * 

 * IPP Compatibility: Destination is not an IPP attribute.
