I backported the documentation patch about 'pdflatexstandalone' to the stable branch here (http://hg.savannah.gnu.org/hgweb/octave/rev/d6f1f46e5b8f).  It will be in the next bug fix release of Octave.

For the original reporter, when switching over to gnuplot you may also need to set the environment variable GNUTERM in the shell to something reasonable.  On my Linux platform the default is 'x11' which produces ugly plots but 'wxt' or 'qt' produce nice plots.

Sorry, the new documentation only made it into
the devel branch. You could download that or wait
for the next release.

Thanks for the quick response.

Using `doc print` in Octave 3.8.1 and 3.6.4 and the online help for 3.8.0 I can't find any reference to 'pdflatexstandalone' though there are a few equivalent options that I have used before.

I will use Rik's solution as I need to print to .png. Once again, thanks for the help.

Or, you could read the help print or relevant
section of the Manual about print options. A
useful snippet is:

               Generate a LaTeX file 'FILENAME.tex' for the text
               portions of a plot and a file 'FILENAME.(ps|eps|pdf)' for
               the remaining graphics.  The graphics file suffix
               .ps|eps|pdf is determined by the specified device type.
               The LaTeX file produced by the 'standalone' option can be
               processed directly by LaTeX.  The file generated without
               the 'standalone' option is intended to be included from
               another LaTeX document.  In either case, the LaTeX file
               contains an '\includegraphics' command so that the
               generated graphics file is automatically included when
               the LaTeX file is processed.  The text that is written to
               the LaTeX file contains the strings exactly as they
               were specified in the plot.  If any special characters of
               the TeX mode interpreter were used, the file must be
               edited before LaTeX processing.  Specifically, the
               special characters must be enclosed with dollar signs ('$
               ... $'), and other characters that are recognized by
               LaTeX may also need editing (.e.g., braces).  The
               'pdflatex' device, and any of the 'standalone' formats,
               are not available with the Gnuplot toolkit.

This is a known issue.  Tex labels are rendered on-screen only with the FLTK toolkit.  For the time being if you need to print you should switch over to the gnuplot toolkit with

graphics_toolkit gnuplot

Marking this as a duplicate of bug #42320 and closing.

Using the default build of Octave 3.8.1 latex labels for plots render correctly. However, if when they are exported using `print` the labels appear as a raw text string.

See the example in the attached files.
