Did you define WIN_PRINT_TEST to use Adrian's test code? (look in print.cpp) You will get two printer dialogs. The second one matters. For me this produces clean vectors.

If there is no support for blur or transparency in the output format you need to mimic it someway. I don't know what Inkscape turns into raster and cairo does.. Search for "ctx->setContextTarget" and try add some lines like these right before:
    //ctx->setPSLevel(CAIRO_PS_LEVEL_3);
    ctx->setTextToPath(false);
    ctx->setFilterToBitmap(true);
    ctx->setBitmapResolution(72);

With save as ps you ask cairo to produce the postscript. With print to a postscript printer I think cairo produces a windows meta file and the printer driver will translate that to a postscript. The white blocks have been said to come because gtk asks cairo for the wrong sort of meta file. at least that is my understanding
