Yes as expected.

Anything, but usually from an editor like geany, on any machine of my 
home network, and it just works.

I have done that  many hundreds of times, both by hand, and from a script 
driven by drivewire, which is a com utility with a legacy computer.

This is ATM, the only kmail install in the local net, the other machines 
are nearly all running some sort of a cnc controlled machine, with me 
writing the gcode with geany, and I generally save the code as a paper 
copy.  And except for kmail, printing an email, it Just Works.

No, tried hpjs and foomatic, foomatic is the cups recommended facility, 
but hpjs fails similarly.

I've wiresharked the data to an mfc-j6920.dw and had to grin a bit, when 
sane tries to access its scanner, or the printer is being accessed, the 
tcp command has a bad checksum the first 6 times the request is sent at 
1 second intervals, but then fixes it and the printer wakes up and does 
its thing, using the brother drivers in that instance. So I can 
appreciate your assessment of their driver "quality". Its not the 
greatest. But it sure beats the hell out of an epson that clogs its 
heads forever in a few weeks. And the expendables are considerably 
longer lasting at about the same cost. This one also does tabloid sized 
paper which is neat when its drawing me a logic diagram captured from 
one of my machines and to get readable text (rockhoppers output is in 
vsg) it still takes 6 to 8 pages of tabloid paper fed thru ps2poster 
from inkscape.

Thanks E. Liddell.
