So Ponders,
What size paper do you print scores on?
I haven’t yet tried to use any other format than A4 (except for printing
brochures on folded A3), although I learned from
<http://www.dante.de/tex/Dokumente/KohmSatzspiegel.pdf> (only in German,
I think…) that the irrational proportions make good typography very
difficult. Yet I have taken inspiration from there to create the
attached tool for making nice margins, which I’ve been using ever since.
Yours, Simon
