Can't print from rear tray

I use a 12.04LTS ubuntu OS and have installed 4.1 LibreOffice. In LibreOffice Calc and Writer, when I print and select the rear tray option, the paper is still printed from Tray 1. The printer works fine for non- Libre Office programs like Adobe pdf. What should I do?

Although I am running 4.0.5.2 on XP/SP3 it could be that you can apply the same.

Open File / Printer Settings

A window opens and gives you access to the “Properties” of your printer. What you see next depends on your printer. I can set there the tray I want the printer to use.
