Hello Frank,

I do not intend to tackle this in the context of the Brother non-free
drivers (if it can be avoided). There is also lots of snipping.

Ok up to there.

This bothers me. Why produce RWG raster and not Apple raster?

Lots of good information. As a cross-check please give what you get
for

  avahi-browse -rt _ipp._tcp

and

  avahi-browse -rt _uscan._tcp

You will have to install avahi-utils.

Cheers,

Brian.
