A print spooler intercepts print information, and then spools it into the printer when it is convenient. It is essentially background printing. This allows for much speedier printing. The actual term spool is an acronym that stands for Simultaneous Peripheral Operation On Line.
Software that manages a print queue and lets print jobs line up one after the other -- as if they were wrapped around a spool -- patiently feeding them to the printer in the background while the user is busy writing novels, crunching numbers.
A software process that accepts a print job from a workstation as if it were a printer and then sends the print job to an actual printer at a later time. There are two styles: a background spooler, where the print spooling process is resident in the same node as the process seeking the print service; and a hardware spooler, where the print spooling process is in a separate node.
Software that accepts a document sent to a printer and then stores it on disk or in memory until the printer is ready for it. This collection of dynamic-link libraries (DLLs) receives, processes, schedules, and distributes documents for printing. The term spooler is an acronym created from simultaneous print operations on line. See also: dynamic-link library (DLL); printer; spooling
