/**
 * Class JobMediaSheetsCompleted is an integer valued printing attribute class 
 * that specifies the number of media sheets which have completed marking and 
 * stacking for the entire job so far, whether those sheets have been processed 
 * on one side or on both. 
 * <P>
 * The JobMediaSheetsCompleted attribute describes the progress of the job. This 
 * attribute is intended to be a counter. That is, the JobMediaSheetsCompleted
 * value for a job that has not started processing must be 0. When the job's 
 * {@link JobState JobState} is PROCESSING or PROCESSING_STOPPED, the 
 * JobMediaSheetsCompleted value is intended to increase as the job is 
 * processed; it indicates the amount of the job that has been processed at the 
 * time the Print Job's attribute set is queried or at the time a print job 
 * event is reported. When the job enters the COMPLETED, CANCELED, or ABORTED 
 * states, the JobMediaSheetsCompleted value is the final value for the job. 
 * <P>
 * <B>IPP Compatibility:</B> The integer value gives the IPP integer value. The 
 * category name returned by <CODE>getName()</CODE> gives the IPP attribute 
 * name.
