Follow-up Comment #3:

Your use case meats many known bugs:
* Bug #33118: The -opengl renderer doesn't handle rotated text (labels here)
better than on-screen and, Octave chooses to use the -painters renderer
instead, even for raster outputs. 
If you are happy with the on-screen result (multiples of 90° rotation), and
that you only want raster outputs (like JPEG or GIF) then you can force the
-opengl renderer


print -djpg -opengl TV1_opengl;


* Bug #48689: You are using the axis command to only show part of the contour
patches, but then you hit a bug in Mesa opengl driver. The output of the
-painters renderer is huge, overly complicated and corrupted, which
Ghostscript (used for conversion to JPEG)  doesn't seem to like on Windows.
Note that on linux it takes ages to get a readable but huge and ugly JPEG
file.
The easiest workaround is to resize your contour instead of changing axes
limits: 


VX=load('MXTV1.txt');
VY=load('MYTV1.txt');
MZ=load('MZTV1.txt');
stop_row = 60;
VY = VY(1:stop_row);
MZ = MZ(1:stop_row,:);
...
axis auto
print -djpg TV1_painters;


* Bug #52764: The warning is due to the non ascii charater "ú". You can
workaround this one using the "-svgconvert" option:


...
axis auto
print -djpg -svgconvert TV1_painters_svg;


Does this cover all the issues you raised?
