I am seeing exactly the same thing in cups 1.1.19 Fedora Core 1.  What 
good is being able to cancel a print job if it does not cancel the print 
job.  I tried substituting the foomatic-rip and serial backend from FC3 
but still have the problem.

I notice that the backend process is ignoring SIGTERM.  i.e. "kill 
procid" will not kill it.  "kill -1 procid" will.

I really need a better solution for my users than dropping to a command 
line, finding the process and killing it with a signal 1.  That's kind 
of embarrassing.

Any assistance is greatly appreciated.
