What does that mean?  Resolution?  How do you convert your PDF to
whatever the printer accepts?

Depends.  For 2.19, you might want to try the effect of the
-dstrokeadjust option.  That might reduce the total amount of line
thickness variation.

That very much appears like you are not properly converting your PDF for
use with the "high quality" printer.

The first thing you are doing wrong is not describing at all what the
images are supposed to be from.  "LilyPond_-_during_input"?  Seriously?
My LilyPond files look like "c16 d e d r4" during input.
