Keep in mind, failover for implicit classes is only available for
clients, as servers are almost never setup to use implicit classes
(the "ImplicitAnyClasses" directive controls that, BTW...)

For normal classes, you should get automatic failover as long as
the backend that is trying to communicate with the printer in the
class stops to allow the other printer(s) in the class to print the
job.  This is the case for all of the backends included with CUPS,
but might not be the case for all third-party backends.

We don't support failsafe or load-balanced printing via Samba, since
Windows doesn't have any real notion of this outside of clusters or
printer pools (manually) pointing to multiple servers.

You might be able to configure a cluster of Samba servers (one per
CUPS server), but I don't know how you'd do that...
