How to Restrict user to Color Print in Xerox WorkCenter 7120 and 7225?

I have 2 of the following products @ the Office:

1. Xerox WorkCenter 7120
2. Xerox WorkCenter 7225

I would like to forcefully restrict the user to stop printing in color envrionment, I know I've to go to every single user and do the following:

Else I can restrict the users from the Admin Panel by going to the Service > Printing > Language Emulations > PCL 6/5e or Else can do it from Accounting which requires XSA to be enabled.

BUT

I require none of these, the basic scenario is this that every user would be (might say) forced as mentioned in the picture and if would like to Print in Color, he/she needs go to the settings and uncheck the Black & White Checkbox.

IS IT Possible?

To Save these settings OR the settings are saved in the Registery so whenever the User LogIn, The settings by default goes to Black & White, if in-case he/she forgot to check the Black & White check box.

Thanx in Advance ...
