A command like
lp -o myoption=whatever ...
will make "myoption=whatever" available for filters and for the
backend as argv[5] (if I remember correctly), see "man backend".

This is not possible with 'lp' or 'lpr' as is but you could make
a wrapper script which determines what you need and then let it
call 'lp' with appropriate special option settings which are
then evaluated by your special selfmade backend.
