Printing with graphics_toolkit FLTK has some known limitations:
- Tex/Latex symbols won't show up in the generated print even if they are visible in the plot window. See bugs #42988, #42320, #42340 which are mostly duplicate entries for the same problem. Should be solved in the meanwhile, see bug report
- Can't print multiline text objects: bug#31468
However there are some ways to overcome these:
Use print [ps|eps|pdf] latex [standalone] for symbols and formulas[edit]
See "help print" for a description of 'pslatex', 'epslatex' 'pdflatex', 'pslatexstandalone', 'epslatexstandalone', 'pdflatexstandalone'
