"You have a network consisting of seven computers running Linux,
all having CUPS installed. You want to change printers assigned to
the class. You can remove a printer and add a new one to the class
in less than a minute. The entire configuration required is done as
all other computers get their default printing routes updated in
another 30 seconds. It takes less than one minute for the whole
change—less time than a laser printer takes to warm up."
