Description Syfer Polski 2020-05-02 21:41:17 UTC 
SUMMARY
The format settings in SystemSettings should expose a setting to change the preferred page format. Currently people who have set all their formats to use metric find themselves with typesetting programs such as LibreOffice producing "letter" formatted documents instead of A4 that's standard around the world.
Changing the format requires writing a value to /etc/papersize, but the discoverability of this option is quite low. The discoverability of this setting in SystemSettings will be much higher and thus it should be exposed here. The minimum two options should be "letter" and "A4".

Setting the region to anything except USA and Canada should set this value to A4 as well.

STEPS TO REPRODUCE
1. Open SystemSettings
2. Go to Regional Settings
3. Go to formats

OBSERVED RESULT
There is no option to change the paper size.

EXPECTED RESULT
There should be an option to change the paper size

Interesting idea. I like it.
Comment 2 Nate Graham 2021-01-06 00:07:22 UTC 
Looks like this will require adding support for reading and writing the LC_PAPER environment variable.

I could give this a try as my first contribution :)

Sounds great! Might be wise to wait until after https://invent.kde.org/plasma/plasma-workspace/-/merge_requests/1147 has landed though, as that merge request changes basically all the code. You can CC yourself on its progress by going there and clicking the little switch by "Notification" on the right sidebar.

Hi, now that this is merged https://invent.kde.org/plasma/plasma-workspace/-/merge_requests/1147

Can I start working on this now or is there something else I should wait on?

Yes, go right ahead now! Thanks again for volunteering to do that.

kcms/regionandlang: Add default paper size (LC_PAPER) customizability

This adds LC_PAPER as a setting to Region and Language settings, so
it becomes possible to choose the default paper size.
