"%d"
in this situation means ["][ token comment ] <other tokens>
--- \gobbleuntil neutralizes \starttyping that changes the catcode of '%'
 ---
so you are left with an open group  (the { before printf)
that needs to be closed.

So the first step is to make '%' a letter token

\starttext
%\tracingall
\gobbleuntil\stoptyping
\starttyping
    { printf("\%d", data); }
\stoptyping
%\tracingnone
This is not more ignored !
\stoptext
