Managing Spoolers, Queues, and Logical Printers
Performing Other Spooler-Related Tasks
The servers become aware that they have lost communications in one
of two ways:
when the supervisor does not receive a response to its periodic
signaling
when the spooler does not receive a response to its requests
Shutting down a server has the following effects on communications:
When you shut down the supervisor, the supervisor notifies all
spoolers containing queues that send jobs to the physical printers
of the supervisor.
When you shut down the spooler, the spooler does not notify the
supervisor. The supervisor becomes aware that communications
with the spooler have been lost the next time it signals the spooler.
