For my understanding BR-Script is a "subset" of PS - it does'nt provide all PS-features (but perhaps additionally other features, which PS does'nt have).

I tried also to print with a Brother in past, which has this "BR-Script" feature, but I don't had success. If it prints, it prints only raw-data or crab (MorphOS).

It seems that a seperate driver is needed - PS, as we know it form our Programs, won't work...... (or have to be post-processed to make it compatible - i don't know).

What I've seen: This printer supports direct pdf-printing. This may help for programms, which provides a pdf-safe support (like Pagestream, VPDF, etc.)
