I'm not sure if I understand correctly. Do you mean that the preview
window is only updated when the preview is finished completely?

I I'm right, this is up to the backend. I guess it uses a big buffer
and returns this buffer to the frontend (xscanimage) instead of
retuening smaller chunks of data during the scan. The only thing you
can do is to ask Brother to change this behaviour.
