Hello Martin,
there are many reasons against using "inside driver color management"
(IDCM that's how I call it, it's not an offical name for it).
1. People who go so far to invest in color management want total
control over this process and don't want to let even the smallest part
of it inside the black box of any printer driver.
2. Most printer drivers do only accept a standard RGB (sRGB) input for
IDCM. That can (yes it will) result in some color losts.
3. For example when using IDCM Canon drivers will automatically select
a profile (one of these canned ones) which matches the Media and
Quality settings you choose in the driver (...no chance to break in
there) and the driver must have a sRGB input then.

Best,
Peter
