The bug is in kde 4.9.3, with okular 1.15.3 (currently not specificable from version dropdown list) Say that you have a 3 page PDF (i.e. page 1, page 2 and page 3), and that you ask okular to print it in 3 copies, using duplexing and collating. You expect Sheet 1, front is page 1 back is page 2 Sheet 2, front is page 3 back is empty Sheet 3, front is page 1 back is page 2 Sheet 4, front is page 3 back is empty Sheet 5, front is page 1 back is page 2 Sheet 6, front is page 3 back is empty Unfortunately, you get Sheet 1, front is page 1 back is page 2 Sheet 2, front is page 3 back is page 1 Sheet 3, front is page 2 back is page 3 Sheet 4, front is page 1 back is page 2 Sheet 5, front is page 3 back is empty Which is quite useless Reproducible: Always Steps to Reproduce: See description
Can you reproduce that behaviour in other KDE/Qt based programs like calligrawords?
KDE 4.9 printing has broken duplex. It occurs in all apps I have tried (kate, kwrite, libre office, okular). See bug 311656, or bug 198795, or one of the many bugs that KDE likes to "resolve" by marking as a duplicates.
No answer for years.
Completely forgot about it. It is fixed in recent KDE, though.
