lprm can't clear the printer once the job has started printing.  It
won't clear the printer cache since it has no way to do that.  Either
cancel the job on the printer after canceling it in cups or turn it off
and back on again (although some printers get pretty confused by that
actually if other things are still queueing data for the port).
