Follow-up Comment #4, bug #44186 (project octave):

I've looked at this a bit.  You are probably correct that the ghostscript
executable is the source of the problem.  Clearly what your conversion tool is
doing and what my conversion tool is doing are quite different.  It looks like
your version of the conversion is using compression (e.g., Lempel Ziv) 

currentfile /ASCII85Decode filter /LZWDecode filter cvx exec

I've attached a diff file that you can use to display the exact command that
is being used as well as to retain the intermediate file.  You may then
experiment.  For example, here is what I see:

>> graphics_toolkit gnuplot
>> surf (peaks)
>> print -dps2write dana2-ps2write.ps
gs_cmd = /usr/bin/gs -dQUIET -dNOPAUSE -dBATCH -dSAFER -sDEVICE=ps2write
-dLanguageLevel=2-dEmbedAllFonts=true -dEPSCrop -sOutputFile="a2-ps2write.ps"

My ghostscript is GPL Ghostscript 8.71 (2010-02-10).  Perhaps you have a newer
version that features better use of compression but may be buggy still.

I would say that if you can read the intermediate file in ghostscript, (e.g.,
"gv /tmp/oct-ynDS7Y.eps"), yet the output that ghostscript creates is
incorrect, then it is likely ghostscript.  Maybe try updating your version of

(file #33013)
