It looks like the eps file isn't recognized as existing when ghostscript is 
called ... and still isn't recognized when unlinked.

Please check that the file is present by adding "dir (opts.ghostscript.source)" 
to __fltk_print__.m in the position indicated below.

  case {"ps", "ps2", "psc", "psc2", "pdf"}
    opts.ghostscript.source = strcat (tmpnam (), ".eps");
    file2unlink = opts.ghostscript.source;
    if (strcmp (opts.devopt, "pdf"))
      opts.ghostscript.device = "pdfwrite";
    else
      opts.ghostscript.device = "pswrite";
    endif
    opts.ghostscript.output = opts.name;
    drawnow ("eps", opts.ghostscript.source);
    dir (opts.ghostscript.source)
    if (opts.tight_flag)
      __tight_eps_bbox__ (opts, opts.ghostscript.source);
    endif
 
Now if you try "print test.pdf", does the dir() command indicate the eps file 
exists?
