How to Fix Missing Duplex Printing Option in Microsoft Word
Question details
Users are unable to find the automatic double-sided printing option in the Microsoft Word print menu.

- Product
- Microsoft Word
- Device & OS
- Windows
- Scenario
- Attempting to print a multi-page document automatically on both sides of the paper.
- Observed behavior
- The duplex, two-sided, or 'Print on both sides' option is completely missing or unavailable in Word's print settings, despite the printer supporting it.
Verify that your physical printer model hardware actually supports automatic double-sided printing, and ensure the printer is turned on and properly connected to your computer.
Enable the Duplex Unit in Windows Device Settings
Activating the duplex unit directly in the Windows Control Panel ensures that Microsoft Word recognizes your printer's double-sided capabilities.
Microsoft Word relies on Windows to detect printer capabilities. If the duplex unit is not marked as installed in the system's printer properties, Word will hide the double-sided printing option.
Press the Windows key, type 'Control Panel', and press Enter. Navigate to 'Hardware and Sound' and click on 'Devices and Printers'.
Right-click on your active printer's icon and select 'Printer Properties' from the context menu. Do not confuse this with 'Properties' at the bottom of the list.
Click on the 'Device Settings' tab at the top of the window. Scroll down to the 'Installable Options' section.
Find 'Duplex Unit' or 'Two-Sided Printing Unit'. Click on it, change the setting from 'Not Installed' to 'Installed', then click 'Apply' and 'OK'. Restart Microsoft Word to see the changes.

Adjust Settings via Word's Internal Printer Properties
Use the manufacturer's specific print properties dialog inside Word if the default drop-down menu fails to show the duplex option.
Update Printer Drivers or Use Manual Duplex
Install the latest drivers to fix software communication bugs, or fallback to manual double-sided printing if automatic duplex is unsupported.
Print Double-Sided Documents Effortlessly in WPS Writer
If Microsoft Word consistently fails to detect your printer settings, switch to WPS Office. WPS Writer offers a highly compatible and intuitive print interface that easily detects hardware duplex capabilities, streamlining your document workflow.
- 1. Open your Document: Launch WPS Writer and open your existing Word document.
- 2. Access the Print Interface: Click 'Menu' in the top-left corner and select 'Print', or simply press the Ctrl + P keyboard shortcut.
- 3. Configure Duplex Settings: Click on 'Properties' next to your selected printer to enable automatic duplex, or simply check the 'Manual duplex' box directly in the WPS print menu.
- 4. Start Printing: Click 'OK' to print your document flawlessly on both sides of the paper.

Frequently Asked Questions
Why does my printer print double-sided pages upside down?
This happens when the binding direction is configured incorrectly. In your printer properties, change the duplex setting from 'Flip on short edge' to 'Flip on long edge' for standard portrait documents.
Can I print on both sides if my printer does not have an automatic duplex unit?
Yes. You can use the 'Manual Duplex' or 'Manually Print on Both Sides' option in the print dialog. Word will print all the odd-numbered pages first, then pause and prompt you to flip the printed stack and re-insert it into the tray to print the even-numbered pages.
Why is the two-sided printing option grayed out in Word?
A grayed-out option usually indicates a communication error between Windows and the printer driver. Ensure your printer is turned on, properly connected, and that the 'Duplex Unit' is explicitly marked as 'Installed' in the Windows Control Panel Device Settings.
Why does duplex printing work in other applications but not in Microsoft Word?
Word is particularly strict about requiring specific status flags from the printer driver. If the driver is slightly outdated or generic, Word may fail to recognize the hardware capability even if basic apps like Notepad or web browsers can. Updating to the manufacturer's specific driver usually resolves this.
