 * Class PrinterState is a printing attribute class, an enumeration, that

 * implementation; it does not have to report every defined printer state. The 
 * {@link PrinterStateReasons PrinterStateReasons} attribute augments the 
 * PrinterState attribute to give more detailed information about the printer
 * in  given printer state.
