samba - Oct 2004 - Print "Job Description" feild

I need to modify the "Job Description" field of an outbound print job.
I'm think this is different that the "Job ID" and "Job
Name" fields,
although I'm not sure.

I am printing from Fedora Core 2 using the stock cups (1.1.20-11.1)
and samba (3.0.7-2.FC2) to various Windows print servers.

Any information would be helpful.

Thanks.
