Spooler Subsystem using too much CPU when idle

[rrobles]

My task manager shows that the Spooler SubSystem App is using 26-28% of the CPU when printer is idle.   Is this normal?  If not, how can I fix this?

Welcome to HP Forums,

This is a great place to get support, find answers and tips,

Thank you for posting your query, I'll be more than glad to help you out 🙂

As I understand, you're in need of support,

Don't worry as I'll be glad to help, 

Although it's normal, I respect your instinct hence I have a few steps you could try:

1. Turn off the printer using the power button and then unplug the printer power cord from the power outlet.

2. Save your work. After using these steps, your current print jobs are lost and will need to be printed again.

3. Open Windows Services using one of the following methods:

   • Search Windows for services, and click Services in the list of results.

   • On your keyboard, press Windows key ( ) + R, type services.msc in the window that opens, and then click OK.

4. Scroll through the list of services and find the name Print Spooler.

5. Right-click Print Spooler and select Stop.

   Figure: Stop selection for Print Spooler Service

   

6. After the service has been stopped, close the service window and use Windows Explorer to browse to C:\Windows\System32\Spool\PRINTERS.

7. Delete all files inside the PRINTERS folder.

8. Shut down your computer from Windows.

9. Make sure you printer has been unplugged for at least 60 seconds, and then plug the power cord into a power outlet.

10. Turn on the printer using the power button on the printer.

11. Turn on the computer and wait for Windows to open.

12. Try printing again and note what happens.

Hope this helps,
