Bug 466861

All my KDE apps use USA letter without an issue.

Can you write specific detailed steps to reproduce? Including setting the locales, languages, formats etc. for your system. Thanks!

This happens on a KDE Neon PC we didn't set any locale, language, format settings--just left default since installation.  The only step is as stated: try to print (preview) from any KDE program such as KATE, Okular, etc., which (though systemsettings says is set to USA letter) are all set on 2L.

Can you supply the following?

- The output of running `env | grep LANG` in a terminal window
- The contents of ~/.config/plasma-localerc
- The contents of /etc/locale.conf

u@Hilltop-Heaven:~$ env|grep LANG
LANGUAGE=en_US
LANG=en_US.UTF-8

#/etc/locale.conf
[Formats]
LANG=en_US.UTF-8

[Translations]
LANGUAGE=en_US

u@Hilltop-Heaven:~$ cat /etc/locale.conf
LANG=en_US.UTF-8
LC_ADDRESS=en_US.UTF-8
LC_IDENTIFICATION=en_US.UTF-8
LC_MEASUREMENT=en_US.UTF-8
LC_MONETARY=en_US.UTF-8
LC_NAME=en_US.UTF-8
LC_NUMERIC=en_US.UTF-8
LC_PAPER=en_US.UTF-8
LC_TELEPHONE=en_US.UTF-8
LC_TIME=en_US.UTF-8

Another thing I noticed in KATE is it lists page margins in millimetres, though Okular lists it in inches... but both are outside printable area (2.96mm or 0.12").  The above is for KDE Neon; of course on my Slackware PC I added British English the above is different, but I'm unsure this actually happened on there... just when I used the network printer I thought it might've.  We installed printer drivers because they seem to work better than the so-called 'driverless', and are unable to delete that one.

Ok, everything on your system looks set up properly for US default print settings. If you're seeing these settings not be respected in the Print Preview window specifically, then that's a Qt bug, since the Print Preview window is 100% Qt code that we don't have control over. The same would be true of the print dialog itself. So I would encourage you to report this issue to the Qt folks at https://bugreports.qt.io/. Once you do, feel free to paste the URL of the bug report in the URL field of this one. Thanks!

kcms/region_language: set LC_PAPER, not LC_PAGE

The correct name of this environment variable/format is "LC_PAPER."
We look for it by the correct name in kcmregionandlang.cpp, but not in
regionandlangsettingsbase.kcfg, causing a mismatch.
