Cancel doesn't kill the backend process in any case.
In this case you must kill the backend process manually.
Use for example
  fuser -v /dev/lp0
to list which processes are accessing the parallel port
and/or use
  fuser -k /dev/lp0
to kill the processes which are accessing the parallel port.

I don't know why cancel doesn't kill the backend process in any case.
