Look at the fonts used. Make sure they are type 1. If not, maybe you need either: \usepackage{lmodern}or \usepackage{cmlgc}
To elaborate a bit on Neal's point, in LyX 1.5.x you can go to Document -> Settings... -> Fonts and set the Roman, Sans Serif and Typewriter fonts to their Latin Modern choices. That will automatically insert the needed \usepackage in the preamble. Alternatively, you can set them to Times Roman, Helvetica and Courier respectively, which are T1 fonts.
In LyX 1.4.x and earlier, you can pick the Adobe T1 fonts from the font menu (I think the choice is labeled 'psfonts'). To use Latin Modern, you need to insert \usepackage{lmodern} in the preamble.
I seem to get pretty good results with the Computer Modern fonts, as well (don't know if that relates to my being on Windoze).
