How to Set a PDF to Print Single-Sided by Default
Question details
The user wants to configure a PDF file so that it automatically defaults to single-sided (simplex) printing when opened and printed by others.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Distributing a PDF form or official document that must be printed on only one side of the paper to ensure correct filling or processing.
- Observed behavior
- By default, printers may use duplex (double-sided) printing based on system preferences, requiring a document-level preset to enforce single-sided printing.
Ensure you are using a professional PDF editor like Adobe Acrobat Pro that allows you to modify advanced document properties and print dialog presets.
Change Print Dialog Presets to Simplex in Acrobat
Modify the document's advanced properties to set the default duplex mode to simplex, forcing the print dialog to select single-sided printing automatically.
PDF formats allow creators to embed print dialog presets directly into the file. By changing the DuplexMode to Simplex, compliant PDF readers will automatically prepare the document for single-sided printing when the user hits print.
Open your PDF file in Adobe Acrobat. Go to the 'File' menu in the top left corner and select 'Properties' (or press Ctrl+D on Windows / Cmd+D on Mac).
In the Document Properties window, click on the 'Advanced' tab located at the top to access print dialog settings.
Locate the 'Print Dialog Presets' section. Find the 'DuplexMode' dropdown menu and change it from 'Default' to 'Simplex'.
Click 'OK' to apply the changes to the properties window. Finally, go to 'File' > 'Save' to ensure the new simplex printing preset is saved within the PDF file.

Easily Manage PDF Printing with WPS Office
WPS Office includes a comprehensive built-in PDF editor that makes it incredibly easy to read, annotate, edit, and print PDFs with precise layout controls.
- 1. Open Your PDF: Launch WPS Office and open the PDF document you wish to print.
- 2. Access the Print Menu: Click the 'Print' icon on the top toolbar or press Ctrl+P to open the print dialog box.
- 3. Disable Double-Sided Printing: In the print settings, ensure the 'Print on both sides' checkbox is left unchecked to guarantee single-sided output.
- 4. Print the Document: Review your other settings and click 'Print' to send the document to your printer in simplex mode.

Frequently Asked Questions
What is the difference between Simplex and Duplex printing?
Simplex printing places content on only one side of the paper. Duplex printing places content on both the front and back sides of the page to save paper.
Why does my PDF ignore the Simplex preset and print double-sided?
Some basic or web-browser-based PDF readers do not fully support advanced PDF properties like Print Dialog Presets. Opening the file in dedicated software like Adobe Acrobat or WPS Office ensures the preset is recognized.
Can I apply the Simplex printing preset to multiple PDFs at once?
Yes, if you are using Adobe Acrobat Pro, you can use the Action Wizard tool to create a batch process that applies the simplex Document Properties to multiple PDF files simultaneously.
Is it possible to lock a PDF so it can only be printed single-sided?
No, print dialog presets act only as a recommended default setting for the print menu. You cannot strictly enforce or lock simplex printing if the end user decides to manually select duplex printing before hitting the final print button.
