The fix is included in Qt 5.11, so I am marking it as affecting only Bionic.

After changing manually, Letter-size pages print correctly, but the setting does not stick. The issue also affects other print settings, e.g. margins, though the aforementioned patch does not deal with these. A similar issue regarding the duplex setting was reported as Launchpad bug 1776173, and subsequently fixed, but other print settings continue to cause problems. Behavior expected: Print dialog would default to Letter paper size, which is set in all available system and KDE preferences, and that was selected for previous prints. Behavior observed: Print dialog always defaults to A4, and page size needs to be changed manually before every print.
