I suggest doing this outside of lynx, with a small shell script, perl
script, C program or whatever you like.  That could split up Lynx's
output into pages (according to your printer's page length) and insert a
Title line for each page.  Or maybe even your lpr (or equivalent) can do
this for you.  Add or change the PRINTER: definition in lynx.cfg to use
your external command.

The only change required in the Lynx code then would be to make it pass
the title to your command.  The simplest way to do this probably would be
to putenv() an environment variable (LYNX_PRINT_TITLE or whatever) before
the relevant `system(buffer);' command under `case PRINTER:', and make
your command use that variable.  The title as seen by Lynx should be
available through HText_getTitle() or HTLoadedDocumentTitle() any time in
printfile() after the HTLoadAbsolute(&WWWDoc) near the top.  (The only
difference between theses two functions seems to be what they return if
no title has been set, NULL vs. "".)

Of course if the "security status" itself is a secret, you shouldn't pass
it around in an environment variable on an unsecure system...
