Please file an enhancement request for this:

     http://www.cups.org/str.php

We'll need the error_log file from the server to see what error is
being returned to the client...

Basically, the current backend interface does not define an exit code
or error policy for this case - we can generally detect when a job is
being rejected for content when printing via IPP, so it should be
possible to extend the supported policies to include a "hold job"
policy that will put the offending job off to the side and print the
rest, or just cancel the job if the destination doesn't support the
print job at all...
