Łukasz, thank you very much for accepting the package into bionic- proposed. I confirm that the updated binary package libqt5printsupport5 fixes the problem. I also updated other libqt5* packages available in bionic-proposed, and did not notice any obvious regressions.
However, I would like to voice my differing opinion on the importance of this bug. While this is perhaps not a high-impact bug in the meaning that it does not impact system stability or security, it is nonetheless one of the "infuriating little bugs" that significantly degrade user experience. For the user who does not remember to dig into prefs to change paper size before every print job, the bug results in the necessity of printing everything twice, as the first copy (A4 on Letter) has top and bottom lines clipped and missing, rendering the printout unusable. This bug, coupled with similar ones and the general instability of KDE desktop, makes Kubuntu 18.04 unsuitable as a desktop OS for everyday use, in my opinion. Because of that I am very grateful that this bug is getting fixed. ** Tags removed: verification-needed-bionic ** Tags added: verification-done-bionic -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to qtbase-opensource-src in Ubuntu. https://bugs.launchpad.net/bugs/1846821 Title: Qt print dialog has wrong default page size Status in qtbase-opensource-src package in Ubuntu: Fix Released Status in qtbase-opensource-src source package in Bionic: Fix Committed Bug description: Please backport Qt patch 213677 to qtbase-opensource-src https://codereview.qt-project.org/c/qt/qtbase/+/213677 [Impact] In Qt5 applications, print dialog (Printer Properties) always defaults to A4 paper size, even when Letter is set as a default in all system and KDE preferences. After changing manually, Letter-size pages print correctly, but the setting does not stick. This impacts users of Qt applications who print things and live in countries where ISO 216 is not default, most notably the United States. [Test Case] 1) Use system settings (KDE preferences, gnome-control-center or system-config-printer) to set the printer size to Letter. 2) Open any Qt application (e.g. KWrite or Falkon). 3) Open a print dialog. 4) Behavior expected: Print dialog would default to Letter paper size and not A4. [Regression Potential] Two possibilities for regressions that I can imagine are: - crashes because something is not defined; - wrong default paper size (A4 wanted but CUPS returns something else). [Additional Information] 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.
