A printer spooler queues up print jobs for later printing. This is a great tool if you are dealing with networked printers or have several computers printing to the same printer. The printer spool will help the printer to print the pages in a queue. In general, consumer grade printers have insufficient memory to store all the pages that you are printing. A printer spool with queue everything to be used later.

This service is required if you have printers with applications that use the printing sub-system (like PDF converters). If this does not fit your needs, you can disable the print spooler service. This will save about 3.8 MB in memory resources. Your printers will still be “installed” if you disable this service, but not visible in the printers folder. After restarting the print spooler, they will reappear and be available for use. I place this service into manual mode and only start it up when printing is required. In manual mode, the service will not automatically start at boot time. However, if you do a lot of printing, automatic mode is the most convenient.

If you have a print spooler error, try disabling and then re-enabling the service again. If this does not work, uninstall the printer and reinstall it again.
