put user in printq group and use Rsh (restricted shell) would be a good way. a user stuck with Rsh as shell cannot cd, so put a link to enq in their home dir. check `man Rsh`, we don't use it.
or write a script (put in root cron) that checks for down queues every 15 minutes, try to bring up say 3 times, then mail or page an admin? avoids having to rely on an operator. might also have a later version do some troubleshooting, like ping and nslookup.
