/**
 * Class OutputDeviceAssigned is a printing attribute class, a text attribute,
 * that identifies the output device to which the service has assigned this
 * job. If an output device implements an embedded Print Service instance, the
 * printer need not set this attribute. If a print server implements a
 * Print Service instance, the value may be empty (zero- length string) or not
 * returned until the service assigns an output device to the job. This
 * attribute is particularly useful when a single service supports multiple
 * devices (so called "fan-out").
 * <P>
 * <B>IPP Compatibility:</B> The string value gives the IPP name value. The
 * locale gives the IPP natural language. The category name returned by
 * <CODE>getName()</CODE> gives the IPP attribute name.
