Excellent!  This worked great.  I only modified LYPrint.c
by inserting the following two code fragments into printfile():


   char *envbuffer = NULL;       /* WebSter Print Mods -jkt */
in the declaration area, and 

   /* Begin WebSter Print Mods - jkt */                
   StrAllocCat(envbuffer, "LYNX_PRINT_TITLE=");
   if (HText_getTitle())
       StrAllocCat(envbuffer, HText_getTitle());
   else
       StrAllocCat(envbuffer, NULL);
   putenv(envbuffer);
   /* End   WebSter Print Mods - jkt */
between the printf(PRINTING_FILE) and fflush(stdout) calls.

As for the external script, it's just a shell script that makes
sure that all of its parameters make sence, then executes
pr -h "$LYNX_PRINT_TITLE" | lp -d $PRINTDEST

Actually, pr is kinda lacking in options.  I'm still looking
for some better formatter.  I'll let you know.

Thanks Klaus!
