How to Fix Duplex Printing and Collation Problems in Acrobat for Mac
Question details
Users need to resolve a printing error where odd-page documents print incorrectly on the back of the next sheet when using two-sided printing and collation.

- Product
- Adobe Acrobat and Reader
- Device & OS
- macOS
- Scenario
- Printing multiple copies of a PDF document containing an odd number of pages with duplex (two-sided) printing and collation enabled.
- Observed behavior
- The final page of the odd-numbered document prints on the reverse side of the first page of the next copy. Additionally, the Collate option remains hidden unless multiple copies are explicitly selected in the print dialog.
Ensure your Mac printer drivers are fully up to date and check your physical printer's capabilities to confirm it supports automatic two-sided printing.
Insert a Blank Page to Make the Page Count Even
The most reliable workaround for the odd-page duplex bug in Acrobat for Mac is to add a blank page at the end of your document.
Because the macOS version of Acrobat struggles to process the transition between copies of odd-paged documents, forcing the document to have an even number of pages prevents the printer from starting the next copy on the back of the previous sheet.
Launch Adobe Acrobat for Mac and open the PDF document you wish to print.
Navigate to the 'Tools' tab and select 'Organize Pages' from the menu.
Click on 'Insert' in the top toolbar, choose 'Blank Page', and place it at the very end of your document.
Go to 'File' > 'Print', set your desired number of copies, and enable duplex printing. Collation will now function correctly.

Configure Native macOS Printer Driver Settings
Bypassing Acrobat's built-in print dialog and using the system-level macOS printer settings can sometimes resolve collation conflicts.
Print PDFs Flawlessly on Mac with WPS Office

- 2. Open Your PDF: Launch WPS Office and open your odd-paged PDF document using the built-in WPS PDF tool.
- 3. Access Print Settings: Click 'File' > 'Print' or press 'Cmd + P' to bring up the comprehensive print dialog.

Frequently Asked Questions
Why is the Collate option missing in Acrobat for Mac?
The Collate option often remains hidden in Acrobat's print dialog until you enter '2' or more in the 'Copies' field. Once multiple copies are specified, the checkbox will dynamically appear.
Is this duplex printing issue specific to Mac?
Yes, user reports and extensive testing indicate that this specific odd-page duplex and collation bug in Acrobat predominantly affects macOS environments.
How do I report this printing bug to Adobe?
You can report persistent bugs or request features by visiting Adobe's official website and submitting a ticket through their dedicated Feature Request or Bug Report Form.
Does adding a blank page use more printer ink?
No. Because the inserted page is completely blank, the printer will simply pass the sheet through or leave the reverse side empty without utilizing any ink or toner.
