 * The supplied value has to be rounded up, so that a range between
 * 1 and 1024 octects is specified as 1 and a range between 1025 and
 * 2048 octects as 2, etc.  This attribute must not include a multiplication 
 * factor from the number of copies which maybe specified in a Copies 
 * attribute.
 * </p>
 * <p>
 * This attribute belongs to a group of job size attributes which are 
 * describing the size of a job to be printed. The values supplied by
 * these attributes are intended to be used for routing and scheduling
 * of jobs on the print service. A client may specify these attributes.
 * If a clients supplies these attributes a print service may change
 * the values if its be able to compute a more accurate value at the
 * time of the job submission or also later.
