JobState is a printing attribute class, an enumeration, that identifies the current state of a print job. Class JobState defines standard job state values. A Print Service implementation only needs to report those job states which are appropriate for the particular implementation; it does not have to report every defined job state. The JobStateReasons attribute augments the JobState attribute to give more detailed information about the job in the given job state. 

IPP Compatibility: The category name returned by getName() is the IPP attribute name. The enumeration's integer value is the IPP enum value. The toString() method returns the IPP string representation of the attribute value.

The job is processing. One or more of the following activities is
occurring:

    
  
  1. The job is using, or is attempting to use, one or more purely
  software processes that are analyzing, creating, or interpreting a PDL,
  etc.
  
  2. The job is using, or is attempting to use, one or more hardware
  devices that are interpreting a PDL, making marks on a medium, and/or
  performing finishing, such as stapling, etc.
  
  3. The printer has made the job ready for printing, but the output
  device is not yet printing it, either because the job hasn't reached
  the output device or because the job is queued in the output device or
  some other spooler, awaiting the output device to print it.

 When the job is in the PROCESSING state, the entire job state includes the detailed status represented in the printer's PrinterState and PrinterStateReasons attributes. 
 Implementations may, though they need not, include additional values in the job's JobStateReasons attribute to indicate the progress of the job, such as adding the JOB_PRINTING value to indicate when the output device is actually making marks on paper and/or the PROCESSING_TO_STOP_POINT value to indicate that the printer is in the process of canceling or aborting the job.

Note: When an output device is stopped, the device usually indicates its condition in human readable form locally at the device. A client can obtain more complete device status remotely by querying the printer's PrinterState and PrinterStateReasons attributes.
