Yesterday I updated LO (mandatory update):

Version: 6.3.3.2.0+
Build ID: 30(Build:2)
CPU threads: 4; OS: Linux 4.12; UI render: default; VCL: gtk3; 
Locale: es-ES (en_US.UTF-8); UI-Language: en-US
Calc: threaded


I have a document to print labels (Avery). 

File / Printer settings, properties. I choose "tray 1 (manual)".

Then File / Print. I Get a new big dialog. I go to properties, and paper tray
is set to "automatic". I change again to "tray 1 (manual)".

I repeat print attempt and in File / Print, and again the tray is set to
automatic. It has forgotten the previous choice. Thus, if I had clicked the
toolbar to print immediately, it would have gone to the wrong tray.


The setting stays put only if "File / Printer settings, options" I activate
"paper tray from printer settings".
