val print : ?subst:( string -> string ) -> [ `Pager | `Plain | `Groff ] -> Format.formatter -> t -> unit

print ~subst fmt ppf page prints page on ppf in the format fmt. If fmt is `Pager the function tries to write the formatted result in a pager, if that fails the format `Plain is written on ppf. subst can be used to perform variable substitution, see Buffer.add_substitute (defaults to the identity).
