/**
 * Class {@code JobKOctetsProcessed} is an integer valued printing attribute
 * class that specifies the total number of print data octets processed so far
 * in K octets, i.e., in units of 1024 octets. The value must be rounded up, so
 * that a job between 1 and 1024 octets inclusive must be indicated as being 1K
 * octets, 1025 to 2048 inclusive must be 2K, etc. For a multidoc print job (a
 * job with multiple documents), the JobKOctetsProcessed value is computed by
 * adding up the individual documents' number of octets processed so far, then
 * rounding up to the next K octets value.
 * <p>
 * The {@code JobKOctetsProcessed} attribute describes the progress of the job.
 * This attribute is intended to be a counter. That is, the JobKOctetsProcessed
 * value for a job that has not started processing must be 0. When the job's
 * {@link JobState JobState} is {@code PROCESSING} or
 * {@code PROCESSING_STOPPED}, the {@code JobKOctetsProcessed} 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
 * {@code COMPLETED}, {@code CANCELED}, or {@code ABORTED} states, the
 * {@code JobKOctetsProcessed} value is the final value for the job.
 * <p>
 * For implementations where multiple copies are produced by the interpreter
 * with only a single pass over the data, the final value of the
 * JobKOctetsProcessed attribute must be equal to the value of the
 * {@link JobKOctets JobKOctets} attribute. For implementations where multiple
 * copies are produced by the interpreter by processing the data for each copy,
 * the final value must be a multiple of the value of the
 * {@link JobKOctets JobKOctets} attribute.
 * <p>
 * <b>IPP Compatibility:</b> The integer value gives the IPP integer value. The
 * category name returned by {@code getName()} gives the IPP attribute name.
