I don't see an option for that, but I also don't see any indication
that we reverse parse that string, we use the job-id to track the job. 

So my untested suggestion is that we/you could remove it from this in
print_cups.c:

	new_jobname = talloc_asprintf(frame,
			"%s%.8u %s", PRINT_SPOOL_PREFIX,
			pjob->jobid, jobname);
	if (new_jobname == NULL) {
		goto out;
	}
