Sorry, I didn't have access to a printer until last night.

As I expected, starting the numbering from 31 doesn't help
either---still blank pages.  (Note that with DejaVu Sans the numbering
from 1 works fine.)

But I also found yet another printer model that doesn't print:
the HP Color LaserJet 4700 (Model Q7492A, Firmware 20060821 46.031.1).

Since you seem to own the only printer that works ;) would
you be so kind and share which model you have?

I also wondered whether bisecting the snapshot-repo would work.
But I only have one LMTX binary; this font handling should be all in
lua code tho?
