We don't have anything in the Job MIB (RFC 2707) that we can pull from for this. Also since these are general job accounting attributes/metrics I would prefer to see them in a separate "Job Metrics" extension specification that can be used for a regular IPP Printers, too.

Again, there is nothing in the Job MIB to support this, so we'll need a separate extension...
> How about adding “job-percent-completed” to indicate how much a job has been completed. May not make sense for small jobs (as they would take less than an hour to print, but if there is a job that takes days or weeks to complete, it might be a useful attribute to add).
CUPS has a "job-media-progress" attribute that provides a percentage of the current page, however it is really only useful for inkjet printers. For large jobs a Client can calculate a "job-percent-completed" value from "job-impressions-completed", "job-impressions", and "copies".
