Setup cups to use color when its the right time
 

I have a problem I dont know how to setup cups to automaticaly use the black cartridge to print black and use color cartridge to print color.

Actualy, when I have only text to print I setup black cartridge in cups

And to print a document with text and picture I setup to use color cartridge but It print both black text and picture with the color cartridge.

Can you help me?

thanks!

We had similar discussion here recently. Solution was to set up the very same printer twice. Once as color printer and second time as black/white.
