I've been trying to cancel a print job but every time I try it cups tells me "Error: client-error-forbidden". I'm logged in as an administrator because I can delete or add the printer and I can stop and start the printer. I did a little googling and the suggestions I tried (editing cupsd.conf to be able to cancel print jobs from any user) did not work. I also tried as root to delete the print job and it said something like "client-error-forbideen" "client-not-found."

Does anyone know what I can do to cancel this print job?
