```julia
julia> @generated function type_print_gen(T)
         return :(println(T))
       end
type_print_gen (generic function with 1 method)

julia> type_print_gen(Int8)
Int8

```

EDIT:  
But this is probably more along the lines of what you want:

```julia
julia> foo(::Type{Type{T}}) where {T} = T
foo (generic function with 1 method)

julia> @generated function type_print_gen(T)
         :(println($(foo(T))))
       end
type_print_gen (generic function with 1 method)

julia> type_print_gen(Int32)
Int32

```
