What do you mean by "code printer"? I suppose suppose that you must mean something more than just producing a string which when parsed and interpreted re-produces the give code? That is what InputForm provides. Which code? Just a function? Or an entire domain written in Spad?
I don't think it makes much sense to write a "Sage code printer" in Spad. Rather Sage needs to be able to process some intermediate representation of a FriCAS expression, for this SExpression is very convenient. That is what InputForm provides.
