Description Grósz Dániel 2024-12-08 02:39:47 UTC

SUMMARY
If I print after scanning multiple pages, it prints all pages even if I select printing only one page.

STEPS TO REPRODUCE
1. Scan two pages.
2. Click Print.
3. Set Page range to 1 to 1.

OBSERVED RESULT
Prints both pages.

EXPECTED RESULT
Prints only the 1st page.

SOFTWARE/OS VERSIONS
Operating System: openSUSE Tumbleweed 20241206
KDE Plasma Version: 6.2.4
KDE Frameworks Version: 6.8.0
Qt Version: 6.8.1
Kernel Version: 6.11.8-1-default (64-bit)
Graphics Platform: X11

ADDITIONAL INFORMATION
The printer/scanner is HP DeskJet 2700e via IPP Everywhere and eSCL.

I set severity to major because it may waste however many pages, or ruin pages that already have something on one side, and you intended to print something else on their other side.

I can reproduce this on Skanpage 24.12.0, Fedora KDE 41.

https://bugs.kde.org/show_bug.cgi?id=436388 feels similar, but I can't reproduce the same issue in Okular 24.12.0, and that one concerns printing to PDF.

Also, AFAIUI, that one is a result of a general Qt limitation w.r.t. printing to PDF, and it concerns complex page ranges, not simple from-to ones.
