Fix PDF Printing Single-Sided When Duplex is Selected
Question details
PDF documents are printing on a single side even when the printer properties are configured for double-sided (duplex) printing.

- Product
- PDF Reader
- Device & OS
- not provided
- Scenario
- Attempting to print a multi-page PDF document using the double-sided printing feature.
- Observed behavior
- The printer ignores the duplex setting and prints the document single-sided.
Ensure your printer hardware actually supports automatic duplex printing and that there is enough paper loaded in the tray before modifying software settings.
Resolve Print Dialog and Printer Property Conflicts
Ensure that the duplex settings in your PDF reader's print dialog match the settings in your printer's system properties.
Sometimes, the PDF application's print settings conflict with the printer's default driver settings. The application might be sending a single-sided command that overrides the printer's duplex preference.
Open your PDF document, click on 'File' in the top menu, and select 'Print' to open the print dialog box.
Look for an option labeled 'Print on both sides of paper' or 'Duplex printing' directly within the PDF reader's print dialog and check the box.
Click the 'Properties' or 'Preferences' button located near the printer name selection. Navigate to the 'Layout' or 'Finishing' tab.
Ensure the 'Print on Both Sides' or 'Duplex' setting in this driver menu is also turned on. Click 'OK' to save, then click 'Print'.

Update PDF Software and Printer Drivers
Outdated software or printer drivers can cause communication errors that prevent duplex printing commands from executing.
Use WPS Office for Reliable Duplex PDF Printing
WPS Office includes a powerful built-in PDF reader that communicates perfectly with most printer drivers, making double-sided printing straightforward and error-free.
- 1. Open PDF in WPS Office: Launch WPS Office and open your PDF document.
- 2. Open Print settings: Click on 'Menu' in the top-left corner and select 'Print', or press Ctrl + P.
- 3. Enable Duplex: In the Print dialog, locate the 'Double-sided' or 'Duplex' option and check the box.
- 4. Print document: Click 'Print' to send the document to your printer for successful double-sided printing.

Frequently Asked Questions
Why does my printer print single-sided by default?
Many printers default to single-sided printing to save processing time or due to factory driver settings. You need to manually enable duplex printing in both the application print dialog and the printer properties.
Does the 'Print on both sides' option disappear if my printer doesn't support it?
Yes, if the installed printer driver does not communicate duplex capabilities to the operating system, the PDF reader will usually hide or gray out the 'Print on both sides' checkbox.
How do I make double-sided printing the permanent default?
Go to your computer's 'Printers & Scanners' settings, select your printer, click 'Manage', and open 'Printing preferences'. Set the duplex or double-sided option to 'On' and apply the changes.
