045/**
046 * The <code>JobImpressions</code> printing attribute specifies
047 * the total size in number of impressions of the documents
048 * of a a print job. 
049 * <p>
050 * An impression is specified by the IPP specification as the image 
051 * (possibly many print-stream pages in different configurations) 
052 * imposed onto a single media sheet. This attribute must not include
053 * a multiplication factor from the number of copies which maybe specified
054 * in a Copies attribute.
055 * </p>
056 * <p>
057 * This attribute belongs to a group of job size attributes which are 
058 * describing the size of a job to be printed. The values supplied by
059 * these attributes are intended to be used for routing and scheduling
060 * of jobs on the print service. A client may specify these attributes.
061 * If a clients supplies these attributes a print service may change
062 * the values if its be able to compute a more accurate value at the
063 * time of the job submission or also later.
064 * </p>
065 * <p>
066 * <b>IPP Compatibility:</b> JobImpressions is an IPP 1.1 attribute.
