Ok, even if for me, it seems very similar. >> On the server, I see all options provided be the driver: >> server $ lpoptions -l -p brother > > I set up a print queue with these Brother DCP-9020CDW drivers by using > 'dpkg -i' with the two packages provided. It was automatically named > DCP9020CDW. How did you get the queue name to be "brother"? I manually installed it if I remember correctly (it was a long time ago). I took the software provided by Brother, but I repackaged it so that it better respects the FHS.

I'm pretty sure that I used the PPD from Brother (and the ones from Canon at work) and that they were not automaticcaly discovered. > For the moment, I am inclined to see the issue as concerning cups-filters. So, if I understand correctly : - before, it worked correctly (with all options) because I manually installed the PPD files on the laptop and cups/cups-browsed do not override them - now, cups/cups-browsed always (for remote queue) generate a PPD file using cups-filters, and the generated PPD is not correct (it misses lots of options available in the remote queue) If this is correct, what should be done ? Is there a way to test what cups-filter generate ?
