========================
I have not checked all the outputs in detail, but they all seem
to be there.

I will try to capture more about the fltk case.

You can do things like ...

test_printing fltk -dpng -debug

... this will only produce png output for the fltk backend, and will display information regarding any system commands used for the pipes. If you encounter a hang, just ctrl-C and try again.

octave:1> test_printing fltk -dpng -debug

backend is fltk

print fltk-png  -dpng -debug

Ghostscript command: '/sw/bin/gs -dQUIET -dNOPAUSE -dBATCH -dSAFER -sDEVICE=png16m -dTextAlphaBits=4 -dGraphicsAlphaBits=4 -r150x150 -dEPSCrop -sOutputFile=fltk-png.png -'

fltk-pipeline: '/sw/bin/gs -dQUIET -dNOPAUSE -dBATCH -dSAFER -sDEVICE=png16m -dTextAlphaBits=4 -dGraphicsAlphaBits=4 -r150x150 -dEPSCrop -sOutputFile=fltk-png.png -'

If you do encounter a hang, make sure there are no m-files in your pwd with the same name as those in ...scripts/plot/...

I don't know why local copies cause Octave to hang for me, but the good news is that I only get one hang per session.
