Hi Norbert,

thanks for the additional information.

Could you possibly do a test whether the problem is fixed with the
upcoming Qt version 5.11 from upstream?

Release candidate 2 has just been released.
You can e.g. download an installer (seems to be available for 64-bit
only) for GNU/Linux from (file
""). This can be run as a normal
user and be installed anywhere for testing, e.g. I quickly tested with
the preselected "$HOME/Qt5.11.0/" (make sure that  "Desktop gcc 64 bit"
is selected for installation).

It won't affect any applications by default, since the system Qt version
will continue to be used instead.
In order to test an application with this Qt version, you need to start
it from the command line with the environment variable 'LD_LIBRARY_PATH'
set to the directory where the corresponding shared libraries are
located, e.g. for my case this was running the following command from
command line:

LD_LIBRARY_PATH=$HOME/Qt5.11.0/5.11.0/gcc_64/lib/ kate

Does your problem problem still occur with this Qt version?
(To verify that the new Qt version is actually used, you can e.g. check
that a new "Advanced" tab is there in addition to the "Page" and "Job
Options" ones after clicking on the "Properties" button in the print
