I hear about CUPS 1.2 advantages for ages now, so I have such a feeling
it's an utopia for next years 8-).

However it's really easy to solve your problem ...
just put this line in root's crontab:

*/5 * * * * lpstat -p|grep disabled|while read a b c;\
do /usr/bin/enable $b;done >/dev/null 2>&1

Cron will check which printer is disabled and enables it
every 5 minutes. If u like notifications only, use this line:

*/5 * * * * lpstat -p|grep disabled|while read a b c;\
do mail -s "printer $b is disabled" you at your.domain </dev/null;\
done >/dev/null 2>&1
