Hi my name is ***** ***** I will be the expert working with you today to help resolve your problem.

Click the lowest selection box, which usually has the name as the application.
Select Printer Features.

Click the Presets Dialog, click Save Current Settings as Presets, provide a name for the preset and save it.
You may now set and save an additional preset for color by setting the Print Color as Gray to Off and Photo Neutral Grays as 4 colors and save it as another preset for color.
The last used preset will remain for future jobs and you may switch easily by selecting the preset according your needs.
