Both buffer and spoolers are used for storing data temporary. The main difference between buffer and spooler is that buffer is used for short term and spoolers are used for long term. Buffer is small and limited while spooler are large capacity to store the data as compare to buffer. For buffer it is necessary to be on line i.e. it is direct communication with computer, on the other hand spool may be either online or offline.
