-(** @deprecated This function is error prone. Do not use it.
-    This function is neither compositional nor incremental, since it flushes
-    the pretty-printer queue at each call.
-
-    If you need to print to some buffer [b], you must first define a
-    formatter writing to [b], using [let to_b = formatter_of_buffer b]; then
-    use regular calls to [Format.fprintf] with formatter [to_b].
