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.

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.

  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.
