what I am trying to achive is the document name being descriptive
I think I understand what you want, and if I am right, it's already there for you.
See screen snap of print job log.
Two days ago, I printed an 8 x 10, which was sent to the spool with a job name as you described. That is very descriptive as it contains date and time to the second so you can pick it out again.
But the good part is the log in Qimage shows what you want. It is very descriptive showing the filename, all the printer settings, every minute detail of the print job.
I believe that is what you were looking for.
Just click FILE and auto job log, and scroll to the File name .... click, and there is all the info you need.
