How about display?

 -- Scheme Procedure: display obj [port]
     Send a representation of OBJ to PORT or to the current output port
     if not given.

     The output is designed for human readability, it differs from
     `write' in that strings are printed without doublequotes and
     escapes, and characters are printed as per `write-char', not in
     `#\' form.

"Peta" is Greek for fifth; a petabyte is 10 to the fifth power, as
well as fifth in line after kilo, mega, giga, and tera.
