Hey thanks,
It's working quite well now, except that I think

users or my unprivileged user the job is not canceled,
I get 403...
But if i type root with NO PASSWORD(my root user does have a pass),
the auth fails but on next try I can cancel the job,
this does not happens if I try to pause the printer..

only when I try to cancel a job.
