Disabling the Print Spooler service stops Windows printing on that computer. Microsoft states that with the spooler disabled you cannot print locally or remotely, and its service guidance adds that you cannot see your printers. Printer installation, network printer connections, and printing in general will fail while the service is off. The effects are limited to printing and printer access. Microsoft’s documentation does not describe unrelated Windows features stopping as a result.
What stops when the spooler is off
The Print Spooler is the part of Windows that selects and loads printer drivers, spools print jobs, and schedules them for output. Microsoft’s description of the service covers exactly these three jobs, so turning it off removes the normal local and remote printing workflow rather than one isolated feature.

In practice that means:
- Printing from the PC fails. Jobs sent from any application to a local printer, or to a printer shared from this computer, cannot be processed.
- Printers cannot be seen or chosen. Microsoft’s Windows IoT Enterprise service table states: “If you turn off this service, you aren’t able to print or see your printers.”
- New printers cannot be installed. Microsoft’s troubleshooting guidance for supported Windows Server versions links a stopped spooler with printer installation problems.
- Network printers cannot be connected. The same troubleshooting guidance associates a non-running spooler with failures connecting to network printers.
Microsoft’s security bulletin MS09-022 uses similar language in its impact description for a historical workaround: “If you disable the Print Spooler service, you cannot print locally or remotely.” That bulletin is covered further below.

The documented consequences concern printing. Microsoft’s material does not say that disabling the spooler makes the whole computer unusable or switches off unrelated services. Two qualifications matter, though:

- The Microsoft guidance establishes what Windows printing does without the spooler. It does not document how every third-party application handles printing. Software that bundles its own printing mechanism may behave differently, so test the specific applications you depend on.
- Machines that are domain controllers have an additional consequence, covered in the domain controller section below.
Choosing whether to disable it
The right answer depends on the machine’s role and whether it needs to print or provide printer access. The table below sets out the four situations the official guidance addresses.
| Machine situation | Effect of disabling the spooler | Documented guidance |
|---|---|---|
| Home or office PC that prints locally or to a network printer | Printing, printer visibility, and printer installation stop on that PC | Microsoft’s service guidance and troubleshooting material describe these failures; disabling is not a practical choice for a machine that must print |
| Windows IoT Enterprise device where printing is not needed | Same printing and visibility loss, with no printing expected on the device | Microsoft’s Windows IoT Enterprise service table marks Print Spooler as okay to disable. This is edition-specific guidance, not a universal Windows 11 recommendation |
| Domain controller where printing is not needed | Printing stops, and automatic pruning of stale printer objects from Active Directory no longer happens | Microsoft Defender for Identity recommends disabling the spooler where it is not required, after reviewing dependencies and active printing workflows. Plan an alternative for stale printer object cleanup |
| Active Directory administration system where printing is not needed | Printing stops on the administration system | Defender for Identity recommends disabling the spooler where it is not required, after reviewing dependencies and workflows |
Home and office PCs
If the PC prints, the spooler is required for that printing. Disabling it removes local printing, shared printing from the machine, and the ability to install or connect printers. Do not expect printing to keep working through Windows while the service is off.
Kiosks and dedicated devices
Where a device never prints, Microsoft’s Windows IoT Enterprise guidance treats the service as safe to disable. That conclusion belongs to that edition’s guidance. Consumer Windows 11 Home and Pro installations should not be presented as following the same table.
Domain controllers and identity administration systems
Microsoft Defender for Identity recommends disabling the spooler on domain controllers and Active Directory administration systems that do not need printing. The reason is reduced exposure on high-value identity infrastructure. The same guidance asks administrators to review dependencies and active printing workflows first.

The printer-pruning trade-off on domain controllers
On a domain controller, the spooler also takes part in removing stale printer objects from Active Directory. Disabling it means that maintenance function stops, so stale entries can accumulate unless another process removes them. Microsoft suggests periodically pruning stale printer objects manually as the alternative.
Microsoft’s ADMX_Printing2 Policy CSP documents the pruning policy and its defaults. Under those defaults, the pruning service contacts published-printer computers every eight hours and allows two repeated contact attempts before it deletes a stale printer object from Active Directory. These are policy setting defaults, not a measure of how common stale printer objects are.
Before disabling the service on a domain controller, decide who will remove stale printer objects, how often, and how you will confirm that no active printer is removed by mistake.
Security context
Microsoft has documented past vulnerabilities in the Print Spooler for which disabling the service served as a mitigation. MS09-022 is one such bulletin. It describes the spooler’s functions and the cost of disabling it, which is loss of local and remote printing. Treat it as historical context. It does not establish that a current, updated Windows 11 machine has the same flaw.

Windows 11 version 22H2 also changed the RPC communications used during printing-related operations, including printing to a printer shared by a server or another computer. Microsoft describes these changes as improving printing security. They do not make the spooler optional for Windows printing, and they do not change the consequence described above.
Disabling and re-enabling the service
To change the service in the Windows interface, open services.msc from the Run dialog, locate Print Spooler, open its Properties, and set Startup type to Disabled. Then select Stop if the service is still running. Restarting the computer applies the setting.
To undo the change, return to the same Properties window, set Startup type to Automatic, select Start, and then click OK. Printers that were installed before the change should reappear once the service is running. If a printer does not return, reinstall it through the normal printer setup process.

Bottom line
Disabling the Windows 11 Print Spooler service stops Windows printing on that computer, including local printing, shared printing, printer visibility, printer installation, and network printer connections. It is a reasonable choice only on machines that do not need to print, and it carries an additional cost on domain controllers, where stale printer object cleanup stops and must be handled another way.
