The first thing I tried was calling cairo_surface_set_fallback_resolution in
evince and calling displaySlice with 300 instead of 72 in poppler-glib, but it
didn't help.

In evince we are only using the gtk+ printing dialog, but not
gtkprintoperation, so it should be done in evince.

It seems there are many changes in cairo git that fix things in poppler/evince.
Do you know if there are plans to release cairo soon?
