okular vs. landscape

I generate plots in pdf form, which are in landscape. I have to use acroread to print them. If I use okular, if I choose 'landscape' from the print dialog, it prints in portrait. If I choose portrait, it prints in landscape, but it doesn't use the whole image area. acroread prints perfectly. Is there any way to make okular work, or some other way to print a damn landscape pdf correctly?
