I'm back at home. Here are the results :

It still far less of what the initial PPD propose. In this case, I think
the main options are present, so it can be enough. But why not all
options are propagated ?

$ driverless ipp://kooot-2.local:631/printers/brother | grep OpenUI
*OpenUI *PageSize/Media Size: PickOne
*OpenUI *PageRegion/Media Size: PickOne
*OpenUI *cupsPrintQuality/Print Quality: PickOne
Now, I understand how it is generated (many thanks), but the result
is indeed very limited (ie few options are present)
I'm sure that my laptop was using the provided one (ie the one
from Brother) because I can see it with 'git diff' (my /etc is
handled with etckeeper). Looking at the history, it appears and
disappears regularly (depending if my laptop is at home or not)
until 2018-03-26 when I added these ppd files in the .gitignore...
What I do not know is where the ppd file was coming from (each time
the laptop was at home, the printer was rediscovered and the PPD file
reinstalled)
Do you want I try to reinstall a stretch system on the local
network to compare ?

Vincent
