How to Fix Mixed Duplex and Simplex PDF Printing Issues
Question details
The user is experiencing an issue where a PDF document prints with a mix of double-sided (duplex) and single-sided (simplex) pages, even though other applications print correctly.
- Product
- Acrobat Pro DC
- Device & OS
- Windows 10
- Scenario
- Printing a multi-page PDF document
- Observed behavior
- The printed output contains an unexpected mixture of two-sided and one-sided pages instead of a uniform duplex or simplex layout.
Verify that your printer driver is up to date and that you have not manually combined separate print jobs in the printer queue.
Standardize Page Sizes and Check Printer Settings
Mixed printing often occurs if the PDF contains different page sizes (e.g., Letter and Legal) or if printer properties are overriding document settings.
A single print job typically uses either duplex or simplex printing. If a PDF contains varying page sizes, the printer may treat the different sizes as separate jobs, resulting in mixed output breaks.
Open the PDF and navigate through the document to see if some pages are differently sized, or view the page dimensions in the Document Properties.
Go to File > Print and click on 'Properties' or 'Advanced' next to your selected printer.
Look for an option such as 'Choose paper source by PDF page size' in the print dialog and uncheck it to force uniform printing onto a single paper type.
Ensure the 'Print on both sides of paper' option is checked and that your paper size is standardized (e.g., A4 or Letter).
Print the PDF as an Image
Printing the document as an image bypasses complex document properties that might confuse the printer and cause irregular page rendering.
Easily Manage PDF Printing with WPS Office
WPS Office provides a robust PDF reader and editor that simplifies printing setups. You can easily standardize page sizes and apply uniform duplex or simplex printing without configuration conflicts.
- 1. Open the Document: Launch WPS Office and open your multi-page PDF document.
- 2. Open Print Settings: Click on 'Print' from the top toolbar or press Ctrl + P.
- 3. Standardize Page Size: In the Print dialog, select 'Fit for printing margins' or 'Custom Scale' to force all pages to print at a standardized size.
- 4. Select Duplex Printing: Toggle the 'Print on both sides' option to ensure consistent double-sided printing, then click Print.
Frequently Asked Questions
Why does my PDF print both single and double-sided?
This usually happens when the PDF contains pages of different dimensions (like Letter and Legal mixed). The printer driver processes these different page sizes as separate print jobs, interrupting the continuous duplex printing sequence.
Can a single print job be configured to mix duplex and simplex intentionally?
Generally, standard printer drivers apply either duplex or simplex to the entire print job. Intentionally mixing them usually requires splitting the document into separate print jobs or using advanced specialized printing software.
How do I force all pages to print double-sided uniformly?
In your print dialog, uncheck any setting that says 'Choose paper source by PDF page size', select 'Fit to printable area', and ensure the 'Print on both sides' or 'Duplex' option is enabled in the printer properties.
