Can someone show me a reference stipulating whether or not that a Canon ip1800 printer blends colors from color wells along with black when it makes black?
If so how can this be averted ? Rev 1.2 of CUPS used to have a whole page of options one could use but they "stupidly" have removed that in rev 1.2.11 along with the option to run black ink only.
If someone knows of a script to force use of black ink only this would be great.
