KDE applications always print A4 paper size

[SUSEtoad]

Leap 15
KDE

KDE applications (Okular, Kate ...) always print Letter-sized documents as A4, causing printer errors and fails.

All page size settings are set to "Letter" in all places.

Other applications (Libre Office, Firefox ...) print correctly.

Was not a problem in Leap 42.3

System settings>Regional settings>Formats allows you to specify KDE defaults which are what all KDE applications will use.

These were all set correctly at setup and - besides - contain no adjustments for printer page size.

Just to try and get a better handle on this, can you please share the output of the following?

locale

and perhaps

egrep -i "defaultpaper|defaultpage" /etc/cups/ppd/*

Did /etc/papersize finally get dropped in 15.0? I still have it in 42.3. Maybe having one containing letter would be of use? My primary DE on openSUSE has always been KDE* or TDE.

Yes, I think it is deprecated. Largely ignored by most applications for years, and CUPS doesn't require libpaper support anyway. The locale LC_PAPER variable is what is relevant AFAIU.

[deano_ferrari]

Just to note that the default paper size set in CUPS for a given printer (and configured in it's respective PPD) does determine what the KDE print dialogue will show by default.

Difficult to test here in Europe -- where a lot of KDE developers are located:

• Leap 15.0
• Printers with A4 paper only -- locale: European -- default printer paper size A4.
• Printing from Kate with the printer set to "Letter" prints OK.
• Generate with LibreOffice Writer a page of size "Letter" and text at the top left, top right, bottom left and bottom right margins; export to .PDF; open with Okular; page size is "Letter"; print with the printer page size set to "Letter" but, with A4 paper loaded in the printer (don't have any "US Letter" paper … ): prints OK.

We need some North American folks with US Letter paper loaded in their printers to test this …

I'm the OP. I can tell you that attempting to print a PDF from Okular or even a TXT from Kate with "Letter" page size onto Letter paper in the printer results in my printer (Canon MF4370) printing one distorted page with print spilling off the edge then throwing an error (on the printer LCD) asking for A4 paper to be loaded.

Printing an ODT from Libre Office or a webpage from Firefox works OK.
