Jean-Michel Elyn <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #1 from Jean-Michel Elyn <[email protected]> --- I can confirm this issue on Arch Linux with a Brother MFC-L8390CDW printer connected via IPPS. Software versions: - Okular: 26.08.2-1 - qt6-base: 6.12.0-3 - CUPS: 2:2.4.20-1 Printer configuration: - URI: `ipps://printer.local:443/ipp/print` - Default duplex setting: `DuplexNoTumble` (long-edge binding) Test results with the same PDF and printer: - Okular: selecting "Long Edge" produces short-edge binding. The selected option remains correct in the print dialog. - LibreOffice: long-edge duplex printing works correctly. - qpdfview (also using Qt): long-edge duplex printing works correctly. - Direct CUPS printing with `lp -o sides=two-sided-long-edge`: works correctly. Since qpdfview uses Qt and prints correctly, the issue appears to be specific to Okular's printing path rather than a general Qt or CUPS problem. The issue is still reproducible with Okular 26.08.2 and Qt 6.12.0. -- You are receiving this mail because: You are watching all bug changes.
