Why are there scanlines or something like it in the fltk plots that

the other option of implementing printing with glReadPixels.

My understanding is that OpenGL triangulates all patches and then draws the triangles. By "scanlines" do you mean artifacts of that process?

I agree that reducing printed resolution to that of a computer display (72 to 140 dpi) would hide those lines, but all other small features would disappear as well. Also, I'm rather attached to the 600 dpi resolution of my printer.

Perhaps there is some other solution for producing output that will hide the triangular mesh?
