Hm, why not? The centronics port of the ST can even be used as input.

An alternative would be the ROM port. There was a project of the German
magazine c't that made a true parallel I/O port of the ROM port. I built
that one back then, and used it as an interface for an EPROM burner.
I could dig that article out (in German) if you're interested.
