/**
 * 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.
