Ok, even if for me, it seems very similar.

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. You can find them here :

According to the date, I made this in 2014 and it was working since.

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.

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 ?
Which information is used by cups-filter to generate the PPD ?

Here are the results from another machine (buster) on the same local net.
If you want the result from the laptop, I can do it later.
$ avahi-browse -rt _ipp._tcp
