Mike, is "color-management" the standard option name in upstream 
CUPS/Mac OS X? Then I will take the same name in 
cups-filters/ghostscript/foomatic-filters to have a standard. This way 
software available for both Linux and Mac OS X, like Gutenprint does not 
need to differentiate.

So this means that for per-job suppression of color management one does 
"lpr -o color-management=false"?
