Can´t move print job

[sidewinder_br]

Hi, I try move a print job on CUPS printer, but i receive
a "access denied" in my log detail. I check everything,
rights, #PreserverveJobs no, well i check all but i can't
move a print job.
Ex.: I have 10 files printing and i like send my job, and
my job is more important so i try move to first position
and I can't. Someone know why?
Sorry for my english...
Best Regards.
