I put "pause (1)" calls before and after each call to the print
function and also removed the

  visible = get (0, 'defaultfigurevisible');
  set (0, 'defaultfigurevisible', 'off');

lines.  Then it mostly runs with the FLTK backend.  There are some
strange effects with the plot windows.  They are displayed (as I
expected) but they are sometimes jumbled.  I have no idea what could
cause that to happen.

Printing the slice demo fails with the following ghostscript error:

A few other plots apparently fail to print because the files are
missing.

I took your page and inserted the fltk plots.  The results are here:

Grab the png files and use them on the Octave Forge site if you'd
like.
