For the sake of clarity: I used an old problem that occured to me a couple
of years ago to illustrate.

It did look correctly in evince when viewed at large magnification, and
eventully turned out to be a bug in the evince printing library. The bug
only showed when printing LilyPond scores and took a very long time to be
taken seriously (and fixed). That's one of the reasons I put this picture
on the web to show what happened.

Many people do not realise that there's a chain of programs active between
the file to be printed and the black spots on the paper.
