/**
* Class JobImpressions is an integer valued printing attribute class that
* specifies the total size in number of impressions of the document(s) being
* submitted. An "impression" is the image (possibly many print-stream pages in
* different configurations) imposed onto a single media page.
* <P>
* The JobImpressions attribute describes the size of the job. This attribute is
* not intended to be a counter; it is intended to be useful routing and
* scheduling information if known. The printer may try to compute the
* JobImpressions attribute's value if it is not supplied in the Print Request.
* Even if the client does supply a value for the JobImpressions attribute in
* the Print Request, the printer may choose to change the value if the printer
* is able to compute a value which is more accurate than the client supplied
* value. The printer may be able to determine the correct value for the
* JobImpressions attribute either right at job submission time or at any later
* point in time.
* <P>
* As with {@link JobKOctets JobKOctets}, the JobImpressions value must not
* include the multiplicative factors contributed by the number of copies
* specified by the {@link Copies Copies} attribute, independent of whether the
* device can process multiple copies without making multiple passes over the
* job or document data and independent of whether the output is collated or
* not. Thus the value is independent of the implementation and reflects the
* size of the document(s) measured in impressions independent of the number of
* copies.
* <P>
* As with {@link JobKOctets JobKOctets}, the JobImpressions value must also not
* include the multiplicative factor due to a copies instruction embedded in the
* document data. If the document data actually includes replications of the
* document data, this value will include such replication. In other words, this
* value is always the number of impressions in the source document data, rather
* than a measure of the number of impressions to be produced by the job.
* <P>
* <B>IPP Compatibility:</B> The integer value gives the IPP integer value. The
* category name returned by <CODE>getName()</CODE> gives the IPP attribute
* name.
