Canon iP6700D can't delete job in cue

Not sure if I can get help here on this problem but I was printing and decided not to continue with the print so deleted it while it was printing Stop/Reset button. It stopped. I had already set another job to print but the deleted job ahead stayed in the cue. When I tried to delete it from the cue I got the message that it couldn't delete it as it was already deleted.
I restarted my iMac, mountain lion still it was there. I unplugged the printer and still it showed.
I cannot print anything until this deleted/undeleted job is gone. Any ideas what I should do?
Thanks so much for any suggestions.
