How to Fix Microsoft Word Crashing When Changing Margins or Line Numbers
Question details
Microsoft Word crashes unexpectedly when adjusting layout elements like page margins or line numbers.

- Product
- Microsoft Word
- Device & OS
- Windows
- Scenario
- Modifying document layout settings (such as margins or line numbering) in Microsoft Word.
- Observed behavior
- Word crashes or freezes immediately when applying new margin settings or enabling line numbers, even when working on completely blank documents. Standard troubleshooting like Office repair and reinstalling do not resolve the issue.
Save your current work in other applications and ensure you have administrative access to your Windows Settings to modify printer configurations.
Set a Virtual Printer as the Windows Default Printer
Since Microsoft Word relies heavily on the system's printer driver to render page layouts, setting a stable virtual printer like Microsoft Print to PDF prevents layout-related crashes caused by faulty drivers.
Microsoft Word is a WYSIWYG (What You See Is What You Get) editor. To ensure documents look the same on screen as they do on paper, Word continuously queries the default printer driver for layout calculations. If your default physical printer is offline, missing, or has corrupted drivers, actions like changing margins or line numbers will force Word to crash.
Changing your default printer to a built-in virtual printer bypasses this hardware driver issue.
Click the Start button, select the gear icon to open Settings, or simply press the Windows key + I on your keyboard.
Click on 'Devices' (or 'Bluetooth & devices' in Windows 11), then select 'Printers & scanners' from the available menu options.
Scroll down to the Printer preferences section and uncheck or toggle off the option that says 'Let Windows manage my default printer'.
Find 'Microsoft Print to PDF' in your list of installed printers, click on it, select 'Manage', and then click the 'Set as default' button. Restart Microsoft Word and try changing your margins again.

Frequently Asked Questions
Why does Microsoft Word need a printer to change margins?
Word calculates page layouts based on the active printer driver's metrics to ensure the document prints exactly as it appears on the screen. If the driver is missing or faulty, this calculation fails and causes the application to crash.
Will reinstalling Microsoft Office fix the margin crash issue?
Not necessarily. If the issue is caused by a missing, corrupted, or incompatible Windows printer driver, repairing or reinstalling Office will not resolve the crash. Updating or changing the default printer is the required fix.
Why does Word crash even when I am working on a completely blank document?
Even blank documents contain default layout settings, such as standard 1-inch margins. When you attempt to change these settings or enable line numbering, Word immediately tries to communicate with the corrupted printer driver to recalculate the page, resulting in a crash.
Do I have to keep Microsoft Print to PDF as my default printer forever?
No. Setting a virtual printer as the default is a troubleshooting step. Once you identify that the printer driver is the culprit, you can update or reinstall your physical printer's drivers to resolve the underlying issue, and then switch your default printer back.
