Hi Robert and Sergio! Sorry for the delay with fixing this. In Qt packaging team, we are all volunteers and work in our free time.
Initially I hoped that one of my co-maintainers would take care of this issue, but looks like they also didn’t have time, so I fixed it myself for the development release. I will look at backporting this change to Bionic and Cosmic soon. Note that I applied only Robert’s patch that fixes duplex printing. For Ubuntu 19.04 we are going to ship Qt 5.12, which should have much better printing experience. If there are other patches that can be backported, please let me know. Also, if one of you adds a test case (steps to reproduce) for the duplex issue to the bug description, it will speed up the stable update a bit. ** Also affects: qtbase-opensource-src (Ubuntu Cosmic) Importance: Undecided Status: New ** Also affects: qtbase-opensource-src (Ubuntu Bionic) Importance: Undecided Status: New -- 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/1776173 Title: qt print dialog shipped with bionic ignores printer defaults Status in qtbase-opensource-src package in Ubuntu: Fix Released Status in qtbase-opensource-src source package in Bionic: New Status in qtbase-opensource-src source package in Cosmic: New Bug description: All kde applications shipped with ubuntu and particularly kubuntu bionic print via the qt print dialog, that, unfortunately, does not seem to respect the defaults set for the printer. Specifically, every time one starts to print the "duplex" option gets reset to "none" even for those printers that were configured for "long edge" duplex by default. This may lead to a huge *waste of paper*: people print, expecting the duplex, do not get it, throw away the printout and reprint, for a total of 3 times the paper usage if the print dialog respected the default. See also https://bugs.kde.org/show_bug.cgi?id=395150 As a final comment and in general, I think that Bionic should be updated to use the QT 5.11 print subsystem (from 5.9.5) as soon as possible (at least via a kubuntu ppa). The QT 5 print dialog has always been extremely poor, with no possibility to provide information about things like print quality and resolution, paper type, stapling (for printers supporting it), etc. Now, QT 5.11 has finally a better print dialog and it would be great if the bionic users could use it.
