/**
 * Class {@code 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()} gives the IPP attribute name.
