 * An impression is specified by the IPP specification as the image

 * 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

 * 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
