Summary
LibreOffice Writer fails to print double-sided documents on my Canon PIXMA TS9560TS, despite duplex working correctly from other applications (e.g., Document Viewer). This appears to be a LibreOffice-specific issue affecting duplex flag handoff to the printer driver.
System Details
LibreOffice Version: 25.8.2.2 (X86_64) / LibreOffice Community
Build ID: 580(Build:2)
OS: Linux Mint 22.2 Zara (based on Ubuntu 24.04)
Kernel: Linux 6.8
UI Render: default
- VCL: gtk3
- Locale: en-AU (en_AU.UTF-8); UI: en-US
-
Ubuntu Package Version: 4:25.8.2rc2-0ubuntu0.24.04.1lo1
Calc Threads: threaded
Printer: Canon PIXMA TS9560TS
Driver Source: CUPS auto-detected via USB
CUPS Version: 2.4.7
Steps to Reproduce
- Open a multi-page document in LibreOffice Writer.
- Go to
File ▸ Print, select the PIXMA TS9560TS. - Enable Duplex Printing (Long Edge).
- Print the document.
Expected Result
Document prints double-sided.
Actual Result
Document prints single-sided only. No error message. The printer retrieves the paper as though it will print double sided, but then sends out the page with the reverse side un-printed. The reverse side prints in a separate page and the process repeats.
Additional Notes
- Duplex printing works fine from Document Viewer and other GTK apps.
- LibreOffice Safe Mode does not resolve the issue.
- Switching to LibreOffice’s native print dialog (
Tools ▸ Options ▸ LibreOffice ▸ General ▸ Use LibreOffice dialogs) does not fix the issue. - Exporting to PDF and printing via Document Viewer is my current workaround.
- I have not modified CUPS defaults to force duplex globally, as this affects other apps.
Request
Can this be confirmed as a known issue? Is there a fix or patch planned? Would be great to align LibreOffice’s print pipeline with GTK/CUPS behavior for duplex support.
