A user requesting a file to be printed will send the file to a "print spooler," which is a type of buffer that holds print jobs until they are ready to be processed by the printer. From there, the printer will often have a "print buffer" that is fed from the print spooler; as that buffer fills, the printer will begin the process of printing the requested document.
