Print Spooler

Windows ServiceMicrosoft Corporation

Also called spooler, spoolsv, print spooler

WindowsMicrosoft

The Windows service that queues print jobs and talks to printers.

What you need to know

This is the print queue.

Print Spooler holds jobs until the printer is ready. A stuck job is a common reason people restart this service. If you never print, you can leave it off.

Need it?: Only if you print or use some scanners
Stuck jobs?: Restart the service, then clear the queue
Safe to disable?: Yes, if you do not print

Feex says

If a printer is "deleting" a job forever, I restart the spooler and clear the queue. I do not reinstall Windows for a stuck PDF.

What does this service do?

Display name: Print Spooler. Service name: Spooler.

The spooler accepts print jobs, stores them, and sends them to the printer driver. Some scan workflows still depend on it.

History on Windows

Still present

The Print Spooler has been a Windows service since Windows NT. The service name Spooler and the host spoolsv.exe are still the contract on Windows 10 and Windows 11.

Why does Windows need it?

Windows needs a queue so an app can finish a print without waiting for every page to leave the printer.

When does it run?

It often stays running so the next job is fast. It wakes hard when a job is stuck or a driver fails.

Should it always be running?

If you print, keep it available. If this PC has no printer and no scan workflow, manual or disabled is a valid choice.

Can I disable it?

Yes, if you do not print

A PC that never prints can disable the spooler. A home office printer needs it. Restarting a stuck spooler is the usual fix, not a permanent disable.

What happens if I disable it?

Print and some scan functions stop. Apps may error when they look for a printer.

Process host

The spooler usually has its own host, spoolsv.exe, rather than a generic svchost.exe group. See spoolsv.exe.

Common problems

Job stuck at "deleting"

Stop the spooler, clear the PRINTERS queue folder, start the spooler. That is the textbook fix.

High CPU

A broken driver can loop. Update or remove that printer. Do not delete spoolsv.exe.

Troubleshooting

Safe steps first.

Restart the service

Services.msc or an admin command to restart Spooler is the first step.

Clear the queue

After the service is stopped, remove leftover files in the spool PRINTERS folder.
