I just checked (10/10/13) and this plot prints fine. I agree that gl2ps is often a problem.

I think that there is wide agreement that the current
fltk/OpenGL-based printing has serious problems. Not only
does it fail when requesting too many or too complex
plots, but since it requires visibility of the plot
it cannot be used for the plots in the Manual, for

It would be great to hear from anyone who knows how
to fix this.

On the positive side, it is my experience that this
printing even in its current state is better than gnuplot.

The attached script runs fine with 3.6.2 up until the last print command. Attempting to print what looks to me like a simple plot results in Octave eating up all system memory.

I've never liked the gl2ps printing mechanism much. It's very slow for even slightly complicated plots. Can we do something better?
