I still don´t get the point:
- How are driver settings and cannend profiles are integrated into the PPD ?
- How is the UI for for the printer chooser generated through the PPD ?
- How is ensured, that the normal user can not change by chance the 
driver settings in the chooser UI, leading to a mismatch of driver 
setting and ICC profile ?

Thes PPD / CUPSicc concept seems still to be weak and intransparent to 
me (and i´m profiling printers since more than 15 years...)

If we want to have successfil user experience for the sRGB workflow with 
cannend profile, we have to find a solution for the mentioned topics and 
we should write down the solution in the OpenICC wiki.

kind regards
