root denied permission to cancel print request???

How is it possible for root to be denied permission to cancel a print
request???

The man pages say root can do it.

I get

    # cancel hp4mv-2972
    hp4mv-2972: permission denied
    #

weirdly, if I su to the user who submitted the job, I can cancel it.

however, I then tried submitting a print job from `lp -d hp4mv < blah`
and found that I could not cancel it. I submitted it as root. I am root.
su-ing to root changes nothing. I simply cannot cancel it.

there are a number of processes associated with the print job, but that
was true with the other job as well. I didn't kill the processes, just
canceled the request and they were killed as part of what the cancel did.

what am I overlooking here?
