[Inkscape-user] Printing Conondrum

I want to print my work out now that I've finished working on it. However it seems as though every portable file format that I can take to the poster-printing place is broken with respect to something Inkscape uses in SVG, the export to bitmap seems to ignore transparencies in certain spots for some reason, the pdf export leaves out whole shapes, and cuts off other shapes, as well as distorting them too, and I don't really think post script will do better than pdf, but I haven't honestly tried that yet.

Is there some way to export my SVG drawing to a portable and printable format that I can take to kinko's?
