Best practice for setting "ErrorPolicy retry-job" on all defined print queues?

[J.B. Nicholson-Owens]

I'd like to set:

   ErrorPolicy retry-job

for all my print queues so that temporary network outages don't stop my print 
jobs (eventually the network will be restored and my print jobs can pick up 
where they left off).

Is the best way to do this via:

- a script which loops over each print queue and setting this with lpadmin(1)?
- setting this once in some class that matches all locally-defined print 
queues? (Is there such a class?)
- some other method I'm unaware of?  If so, what is that method?

The second option seems more reasonable to me.  As I add and remove printers 
that method would continue to work.  If I have to loop over each print queue 
and set this with lpadmin(1) I'm liable to forget to do that when I add a 
printer and then wonder why failing jobs to that printer aren't automatically 
being retried.

Thanks.
