I have upgraded Lightroom from a version 3 to the latest Creative Cloud, and am having problems. The first is that I can't find a print preview option -- can't believe they have eliminated it. The paper size menu did not include 17x22, so I make do with A2. (I could custom enter 17x22 on my new Canon 1000. At the moment, it insists on printing 14x21 in print in the vertical mode, with size reduced to fit. I'm sure I am doing things wrong, but it would nice to have a preview to see what the system is giving me.
