Set print layout to one page

I moved recently to Libre office from Microsoft office.
I’ve tried to open an existing document and it open all right, with the only difference that in print layout view i see two pages at a time.
I’ve tried to change that to one page, my favorite, without success.
Can any one tell me please how to do it.
I run
LibreOffice Build ID: 350m1(Build:2)
under Ubuntu 12.04 Precise Pangolin

Thanks !!!

Select Menu “View” → “Zoom...”, this will open the “Zoom and View Layout” dialogue:

To display a single page using print layout, select “Single page”. “Columns” arranges multiple pages side by side.
