[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}.
