How to export a selection in Calc as PDF?

When I click on “Export as PDF”, I see in the GUI that I could export only cells selected, but I can’t, because this form in the GUI is deactivated.

I’m on Debian/unstable with Libreoffice 4.1.1, does I miss any requirement ? (a poppler package or anything else ?)

Choose Format - Print Ranges - Define and then export to PDF

I didn’t know this menu. It worked, thanks !
