Package: CUPS Version: 1.7.5 I just found out that on the CUPS page when defining (or modifying) a printer the "Color Calibration Mode" check box only appears only when the language of the desktop is set to English.
I found this because I'm French and using a french desktop on GNOME Shell. But this option was on a new box I had installed without all locales, so defaulting to English. I can confirm this, by switching from English to French and back the option "Color Calibration Mode" is present or not. Attached are two screen shots with the pages in French and in English. The screen shots are taken from the same computer. The only change was the default language.
