Since installing KDE 17.10, I can not print in landscape mode. No matter the application (LibreOffice, Abi, Appache Office). I tried to go through a PDF format, but that does not work either. Obviously, I have no accessible control (cups, printer control panel, application interface) to allow me to fix the problem.
This would be a bug in the Qt print dialog, which KDE has no control over. Please report it upstream to the Qt folks if you can still reproduce the issue with a recent Qt version (e.g. Qt 5.12 or later).

I am now on Kubuntu 19.04 and I no longer have the problem with printing in landscape mode. So, I think the ticket may be closed.
Great.
