ISO DPA: Job-page-count
This attribute contains the number of source pages in the job
that the server expects to image. The server shall compute this
value by the following procedure:
a) For each document in the job object, multiply the value
of document's page-count attribute by the value of its copy-
count attribute and call the result document-set-page-count.
b) Add up all the document-set-page-counts from the previous
step and call this sum the job-copy-page-count.
c) For each job-result-set, multiply the value of job-copy-
page-count from the previous step by the value of job-copies
element of the job-result-set and call the result job-result-
set-page-count.
d) Add up all the job-result-set-page-counts from the
previous step and set this sum into the job-page-count
attribute.
The value of this attribute is a measure of the amount of
computation involved.
The accuracy of this value is dependent on the accuracy of the
page-count attribute in each document. If some documents have
a page-count value of 0, the server may set the value of this
attribute to 0 and not use it for scheduling.
