Okular does not use system-wide printer settings

[Bruce Veidt]

Printer settings (via CUPS or System Settings -> Printers) have letter paper and duplex specified. When printing from okular, settings used are A4 paper and non-duplex printing so every print job requires manual setting of the correct printer settings. These changes are not stored. Other non-KDE applications, such as LibreOffice or Firefox, correctly use the system settings. This behaviour is repeatable and has been observed on both Kubuntu 18.04 systems that I use.

I expect okular (and other KDE programs) to print according to the setup in System Settings -> Printers and not use a hard-wired default.

Status changed to 'Confirmed' because the bug affects multiple users.

I just switched from Xfce to KDE. I'm experiencing the same problem with Okular Version 1.9.3 on a new installation of Kubuntu 20.04.

In addition to what Bruce reported, I also tried changing the printer setting from "Letter" to "Letter/ANSI A," but that made no difference.

I then tried printing the document with qpdfview 0.4.18, which worked as expected (I'm noting this because I'm not sure if this is considered a KDE application or not). One thing I did differently than Bruce is that I was printing duplex.
