spool: vi. [from early IBM `Simultaneous Peripheral Operation
On-Line', but is widely thought to be a backronym] To send files
to some device or program (a `spooler') that queues them up and does
something useful with them later. Without qualification, the
spooler is the `print spooler' controlling output of jobs to a
printer; but the term has been used in connection with other
peripherals (especially plotters and graphics devices) and
occasionally even for input devices. See also demon.
