The total size in number of impressions of the document(s) submitted.

In computing this value, the server/device SHALL NOT include the multiplicative factors contributed by (1) the number of document copies, and (2) the number of job copies, independent of whether the device can process multiple copies of the job or document without making multiple passes over the job or document data and independent of whether the output is collated or not. Thus the server/device computation is independent of the implementation and reflects the size of the document(s) measured in impressions independent of the number of copies.

See the definition of the term 'impression' in Section 2.
