Googling seems to indicate this is a deeper bug than the app (gnome-print was blamed in one report, but it seems deeper than this.). I also had similar problems with modifying the SLUG bootcamp flyer in inkscape - it didn't seem to like partially opaque objects. You may also find that the issue dissapears/changes if you use a different printer, for instance from PCL to PostScript.
My simple suggestion would be to create a copy of the png and use imagemagick to add a white canvas underneath - but this probably breaks the fact you don't want to mod the image. At least you could probably script this to be fairly automagic.
