Hmm, well as long as you have added a handler for SIGTERM (that
ideally should set a "job canceled" flag and return), the filter
should be able to do any necessary cleanup and write any number of
messages to stderr (which should show up in the error_log file...)
It would help to know what version of CUPS you are using and what
Linux distro...
