  32 /**
  33  * Class {@code JobKOctetsProcessed} is an integer valued printing attribute
  34  * class that specifies the total number of print data octets processed so far
  35  * in K octets, i.e., in units of 1024 octets. The value must be rounded up, so
  36  * that a job between 1 and 1024 octets inclusive must be indicated as being 1K
  37  * octets, 1025 to 2048 inclusive must be 2K, etc. For a multidoc print job (a
  38  * job with multiple documents), the JobKOctetsProcessed value is computed by
  39  * adding up the individual documents' number of octets processed so far, then
  40  * rounding up to the next K octets value.
  41  * <p>
  42  * The {@code JobKOctetsProcessed} attribute describes the progress of the job.
  43  * This attribute is intended to be a counter. That is, the JobKOctetsProcessed
  44  * value for a job that has not started processing must be 0. When the job's
  45  * {@link JobState JobState} is {@code PROCESSING} or
  46  * {@code PROCESSING_STOPPED}, the {@code JobKOctetsProcessed} value is intended
  47  * to increase as the job is processed; it indicates the amount of the job that
  48  * has been processed at the time the Print Job's attribute set is queried or at
  49  * the time a print job event is reported. When the job enters the
  50  * {@code COMPLETED}, {@code CANCELED}, or {@code ABORTED} states, the
  51  * {@code JobKOctetsProcessed} value is the final value for the job.
  52  * <p>
  53  * For implementations where multiple copies are produced by the interpreter
  54  * with only a single pass over the data, the final value of the
  55  * JobKOctetsProcessed attribute must be equal to the value of the
  56  * {@link JobKOctets JobKOctets} attribute. For implementations where multiple
  57  * copies are produced by the interpreter by processing the data for each copy,
  58  * the final value must be a multiple of the value of the
  59  * {@link JobKOctets JobKOctets} attribute.
  60  * <p>
  61  * <b>IPP Compatibility:</b> The integer value gives the IPP integer value. The
  62  * category name returned by {@code getName()} gives the IPP attribute name.
