Print Spooler is a service that manages your printing devices connected to the computer. It retrieves the location of the print driver, schedules printing etc. If you don’t use a printer and don’t plan on using one, you can turn off this function to gain more productivity and internal memory for your computer.
To disable the Print Spooler service (in case you never use a printer), on Windows 7, follow these steps:
1) Click on Start button and type services.msc in the search field. Then, press Enter.
2) In the Services window, look for the following entry: Print Spooler.
3) Double click on it and set the Startup type as Disabled.
4) Finally, click OK to validate.
