Is it possible or practical to examine a printer's internal queue for jobs that might include this (completely optional) CreationDate field?
If not, then: I'm not sure that the distinction means anything. :)
Yes. Many printers have a web interface where you can see active jobs, job history, timestamps, and document information. Some even have a physical control panel that lets you inspect this information directly from a touchscreen.
