Then change:
ps_init+=[ bannerline ]
TO
ps_user_opts+=[ bannerline ]
and now they can do: lpr -Zbannerline

Not really easily.
You would have to modify ifhp.c:
char *Find_sub_value( int c, char *id, int strval )
{
char *s = 0;
int i;
DEBUG4("Find_sub_value: type '%c', id '%s'", c, id );
if( s == 0 && !strcasecmp(id,"pid") ){
static char pid[32];
SNPRINTF(pid, sizeof(pid),"%d",getpid());
s = pid;
}
/* pretty date */
if( s == 0 && !strcasecmp(id,"date") ){
static char date[64];
struct tm tm;
gettimeofday(&tm);
strftime(date, sizeof(date),"format for date",&tm);
s = date;
}
Now change
/date (\%s{D}) def
TO
/date (\%s{date}) def
and you will have what you want.
Of course you could even go further and use:
ifhp.conf file:
date_format= .... format for strftime ...
/* pretty date */
if( s == 0 && !strcasecmp(id,"date") ){
static char date[64];
char *fmt = Find_str_value(&Model,"date_format");
struct tm tm;
if( date_format ){
gettimeofday(&tm);
strftime(date, sizeof(date),Date_format,&tm);
s = date;
} else {
id = "D";
}
}
But I digress again.

Well, you have the code there... :-)
