Mind you, they still do. No idea WHAT they test in WHQL testing, but it doe=
s not make a lot of sense to me.

Provided we use them :) But basically something QA should do anyhow before =
releasing the driver. The question is if this is a "LSB job".

An absolute "must". Something like a three page "Dr. Grauert letter" in A4/=
letter could be a minimum requirement for monochrome/office, adding color a=
nd graphics would make it slightly more complicated. Some finishing might b=
e added for top scores...

With PDF samples showing how they should look like, maybe ?

Feeds MUST work if supplied or optional, but that's something QA should hav=
e checked already.

Possibly even build and install. Documentation should be there, too.
Some device functions might only be available via closed source utilities -=
while I believe this to be utterly wrong, this is sometimes the only possi=
ble solution due to legal reasons. But the scope for both open source and c=
losed source functionality should be documented.
(Again, this is a personal opinion. It can and possibly will differ from th=
e position of my employer.) =
