[cups-devel] how to get job titile with its full name

[liu3]

 Dear Mike, 
             In the last post,  you wrote 
"You can't. The original file name is never passed, and generally speaking you don't have access to that file anyways."
Actually, I am working on a printing audit porject, we must audit the file name with its full name, and my system is using cups 1.4.2, 
could you give me some more advice? 
            Thank you very much, best regards.
