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:
  Fix Committed
Status in qtbase-opensource-src source package in Cosmic:
  Fix Committed

Bug description:
  [Impact]
  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.

  [Test Case]
  1) Install a printer that can duplex and configure it to do duplex with 
long-edge binding from the printer setup dialog.

  2) Open a PDF with okular, and open the print dialog. Select the
  printer above.

  3) Press the "Options" button to enlarge the dialog to also present
  the options. Select the "options" tab, right of "copies". Verify that
  Duplex Printing is preset to "None"

  This is wrong, because the printer was configured to do duplex with
  long-edge binding.

  4) Print and close okular.

  5) Reopen okular (with the same or another PDF file). Open again the
  print dialog and select the same printer.

  6) Redo 3). Again see that Duplex Printing is preset to "None",
  instead of being at the default or at the previously used setup.

  [Regression Potential]
  The proposed patch only changes the default settings. The regression 
potential may be that the values are wrong, although they are already wrong.

  In case there is some bug it may lead to crashes. But this code is in
  the latest stable Qt release and I am not aware of any such crashes
  reported.

  [Other Info]
  The proposed patch is a backport of the following upstream commits:
  - https://code.qt.io/cgit/qt/qtbase.git/commit/?id=f6fd3f18d301cde3
  - https://code.qt.io/cgit/qt/qtbase.git/commit/?id=fa854f214a3c812e

  [Original Description]

  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.
