I don't know about the other threads in this thread, but long ago I
solved the light typeface on white background by switching to TeX Gyre
Schola, TeX Gyre Heros, and TeX Gyre Cursor fonts. On the Doc settings
fonts window, I had to check "Use non-TeX fonts", and had to compile it
with LuaTeX and LuaLaTeX.

These Century Schoolbook lookalikes look great on paper too.
