# Slideshow export to PDF (landscape)

I am trying to export a slideshow presentation that I have created in Mathematica 8 to PDF in case I have trouble connecting my laptop to a projector for a talk I am giving. I have tried Save As, Save Selection As and Print to File after setting the print setting to landscape.

The latter produces the enormous file even though I am rasterizing the plots, and the former save my file normally but in portrait and also lose the Scaled option of plots. Does anyone have a good workflow for this or know a good reference?

On Mac OS 10.6, Mathematica 9.01. I took a slide notebook (which was already in landscape mode) went to File->Printer Settings-> landscape then Print->.Print as pdf and it came out in landscape mode. –  bill s Jun 18 '13 at 2:19
@bills I have now done this the way you suggested. This is what I was doing but I hadn't manually rasterized every image, instead I had added a 2d transparent prolog to all images to force rasterization. It turns out that this works for every other export to pdf but not Print as pdf. I'l leave this open in case someone illuminates me as to WHY but I have a talk at least! –  gpap Jun 18 '13 at 6:10

@Silvia this is GREATLY helpful and I've upvoted it. Thanks a lot! –  gpap Jun 19 '13 at 9:19
@YvesKlett thanks, I answered as per your recommendation. Will give it a couple more days before accepting - I think if someone else gave me the answer I'd accept only if I was convinced there is nothing better one can do. –  gpap Jun 19 '13 at 14:46
