All right...
Please, in /etc/init.d/cupsys, replace line:
start-stop-daemon --start --quiet --oknodo --pidfile "$PIDFILE" --exec $DAEMON
with line:
start-stop-daemon --start --quiet --oknodo --pidfile "$PIDFILE" --exec /usr/bin/strace $DAEMON &> /tmp/cupsys-strace
install strace package and restart CUPS. Try printing to remote printer and, when it fails (after minute or two), stop cups and attach /tmp/cupsys-strace. This could be a very large file :/
