Hello,
I mean, the parameters are not formated unless the function is forced.

Have you looked at Printf.kfprintf and ikprintf (which is >= 4.00
iirc) ?

let delayed_sprintf fmt = Printf.sprintf (fmt ^^ "%s");;
# let result = Printf.sprintf "%d) %s\n" 3 "foo";;
val result : string = "3) foo\n"
# let thunk = delayed_sprintf "%d) %s\n" 3 "foo";;
val thunk : string -> string = <fun>
# thunk "";;
- : string = "3) foo\n"

Maybe something like:
*let lazy_printf =*
* let k s = lazy (sprintf "%s" s) in*
* ksprintf k*
