With Cairo, you can definitely produce SVG. And as Duncan has pointed
out, in the next release you will be able to use the PS/PDF backend.

With respect to real printing, we could give it a go, but Duncan's
apiGen tool (which saves us a lot of work when adding a new module)
can't currently do the printing modules and, thus, we'd have to do that
all by hand. I could offer to bind a rudimentary printing functionality
for the next minor release.
