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.
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.
As with JobKOctets, the JobImpressions value must
not include the multiplicative factors contributed by the number of copies
specified by the 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.
As with 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.
IPP Compatibility: The integer value gives the IPP integer value. The
category name returned by getName() gives the IPP attribute name.
