Well, yes, and I am not sure (at least not yet) if print jobs for a
class are diverted to other members of the class or not. It seems
that data kept in the printer buffer and in the print-server the
printers are connected to can make it difficult to figure what is
actually going on.
A much bigger problem are printers that are not members of classes,
though. Such printers are not members of classes because they are at
physically different locations, and employees would have to go to from
one printer to another to collect the lables.
Yet if a printer doesn't print anymore, it is desirable to divert jobs
to another printer, preferably a designated fallback. It is of no use
when the jobs get stuck in the queue until the printer is being
maintained which can be days later.
