I wish to create a pdf-file out of a tex-file, so that the text is printed in two columns, and pages are to have the landspace orientation. The standard way to do this, as I see on the Net, is to say
\documentclass[landscape,twocolumn,letterpaper]{article}
However on my system (Win 7, MiKTeX 2.8) it produces a pdf-file with the "portrait" pages. What's the reason of that?
