Hi Pascal and Mike,

[Thanks Mike for the pointer - I think I've tracked down the answer]

The result of the recent Open Printing thread on "no color management"
was this note sent by Joe Simon on 12 June:

Hi everyone,

Rev. 7225 of 'cups-filters' now replaces "no-color-management" with
"cm-calibration" for the bool option. So the following commands should work
without the added '=' symbol, and will disable ICC profile management:

$ rastertopdf 1 foo bar 1 "cm-calibration" input.ras >>output.pdf
$ foomatic-rip -p foo -o cm-calibration

Joe Simon

Cheers,
- Ira
