Erlang io:formatting a binary to hex

Question

Can I format an Erlang binary so that each byte is written in hex? I.e.,

> io:format(???, [<<255, 16>>]).

Improving upon @hairyhum

This takes care of zero paddings << <> ||<> <= Id, Y <- integer_to_list(X,16)>>

reverse transformation <<<> || <> <= Id,Z <- [binary_to_integer(<>,16)]>>, %%hex to binary
