Probably a Qt 6 print stack problem, but before escalating in Qt bugreport website I would like to first start here, since it's the place where I originally experienced the problem. In Okular printing options, you can find: Print range: - Print all - Pages from ... to ... - Pages - Current page - Selection I had to print two pages of a PDF document I cannot share publicly, with double sided printing. So I selected "Pages" option and I wrote 479-480, selected "double sided printing" "long side binding" and pressed "print" button. The printer did not start (debug CUPS infos attached in file cups_not_working_journal.txt). If I instead use the option "Pages from 479 to 480" the printer works (debug CUPS infos attached in cups_working_journal.txt). Okular 24.02.1 KDE Frameworks 6.0.0 Qt 6.6.2 Plasma 6.0.3 CUPS 2.4.7
