Strange. I still don't see the text on-screen. But I guess this is not
related to printing then, but rather a rendering issue.

Hmm, does that make it a feature then? (that's an honest question as I
don't really know) I do find it strange that I don't see the edges on
screen, but I see them in the figure. Generally, I think printed output
should match the on-screen output as well as possible.

That could be, but shouldn't the edges be visible on-screen as well
then? Perhaps it's a gl2ps thing?
