Comment 23 for bug 630639

you will need two files, print_win32_vector.py and print_win32_vector.inx, available from Bug 966244, comment 15, and comment 4. Alternatively you can get them from the Inkscape repository at:
http://bazaar.launchpad.net/~inkscape.dev/inkscape/trunk/files/head:/share/extensions/

you will need to copy these two files into the directory \Inkscape\share\extensions\ and then in Inkscape you can use the (new) menu item Extensions->Export->Win32 Vector Print.
I am not entirely sure if this will run as-is on your machine because it depends on which version of Inkscape you are currently running, but give it a try, and if there are error messages then report them here, together with the version number of your Inkscape.

hth,
