How to Prevent Double-Sided Copies from Mixing Pages in PDFs
Question details
Users need to stop the printer from printing the first page of a new copy on the back of the last page of the previous copy when making collated double-sided prints.
- Product
- Device & OS
- not provided
- Scenario
- Printing multiple collated double-sided (duplex) copies of a document that has an odd number of pages.
- Observed behavior
- The final page of one document copy prints on the reverse side of the first page of the subsequent copy due to the continuous duplex printing process.
Check your PDF document's total page count before printing. If it is an odd number, the printer will naturally use the blank back of the last page to start the next copy when collating.
Insert a Blank Page at the End of the PDF
Adding a blank page to the end of your document makes the total page count even, ensuring each new copy starts on a fresh sheet of paper.
This is the most reliable method because it modifies the document itself, preventing printer driver variations from causing the issue. By forcing the document to have an even number of pages, the printer will print the blank page on the back of the last odd page, leaving the next physical sheet ready for copy number two.
Launch your PDF reader or editor and open the file you intend to print.
Scroll to the final page of your PDF document.
Use the page management or insertion tool in your software to add a single blank page at the very end.
Save the updated PDF, open the print dialogue, select double-sided printing, and proceed to print your collated copies.
Adjust Advanced Printer Settings
Modify your print dialogue settings to prevent the continuous flow of duplex printing across collated sets.
Easily Manage PDF Pages and Print Settings with WPS Office
WPS Office provides a comprehensive suite of PDF tools, allowing you to quickly insert blank pages, manage document structures, and perfectly configure duplex printing without hassle.
- 1. Open your PDF: Launch WPS Office and open your odd-paged PDF document.
- 2. Insert a blank page: Navigate to the 'Page' tab on the top ribbon, select the last page, and click 'Insert Blank Page'.
- 3. Configure print settings: Press Ctrl+P, select 'Print on both sides' (Duplex), ensure 'Collate' is checked, and click 'Print'.
Frequently Asked Questions
Why does my printer mix pages when printing double-sided copies?
When a document has an odd number of pages, the back of the final printed sheet is technically left blank. If you print multiple collated copies, the printer automatically starts the next copy on that blank back side to save paper.
Does collating affect double-sided printing?
Yes. Collating tells the printer to print the entire document in order before starting the next copy. In duplex mode with an odd page count, the continuous printing process bridges the end of one copy and the start of the next.
Can I fix this without modifying the PDF document?
Some advanced printer drivers allow you to insert a separator page between copies or have an option to 'Print as separate jobs'. You will need to check your specific printer's 'Properties' or 'Advanced Settings' in the print dialogue.
