I submitted a changeset in March which explained how
to use 'pslatex'
but, this may not have been applied to the stable branch.

I documented that the OpenGL based toolkits do not support the tex renderer for printing in this changeset on the stable branch (http://hg.savannah.gnu.org/hgweb/octave/rev/c4ffcc961f3c).

Closing report.

Right, printing does not work, as
reported in #42320.

I just checked the display, without
noticing the "printing" in the report.

The current Manual does explain how to work
around this. (At least if the patch that I
supplied got applied.)

This should probably be reported as duplicate of

There should be a note about this in the documentation.  Currently, the Tex parser works for on-screen rendering, but not with the simple print output formats.


text (0.5, 0.5, '\gamma');
print tst.pdf

The resulting PDF file has only 'gamma', rather than the gamma symbol.  See alsobug #42320.

Your example works correctly using fltk in the
current development system. I believe that
the fix for this will be in the next release,
if not in the current release. (You did not mention
what version of Octave you are using.)

Also, the Manual has recently been updated to more
fully describe use of TeX, including how to
make use of the standard TeX system for annotating

In any case, this report can be closed.

Figure 15.7 of the manual is meant to demonstrate the use of tex macros in text objects. It took me some time to find out that generating print output from that figure currently only works for the gnuplot backend. A short hint in the manual would be helpful.
