The format call can be substituted with writefln directly:

void main(string[] args)
{
     import std.algorithm, std.format, std.stdio;
     enum cols = 16;
     args[1].File("rb").byChunk(16).each!(chunk =>
         writefln!"%(%02X %)%*s  %s"(
             chunk,
             3 * (cols - chunk.length), "",
             chunk.map!(c =>
                 c < 0x20 || c > 0x7E ? '.' : char(c))));
}
