Is there a setting for black and white printing from iOS?

I have a color printer that supports airprint but I don't want to waste the color toner on random docs. Is there a setting in iOS (iPhone, iPod, iPad) that would allow me to override and print black and white?

With iOS 9 AirPrint now has the option to print Black & White.

There doesn't seem to be a way to do this natively.

Your options seem to be:

• Get a black-and-white airprint printer.
• Use a black-and-white, non-airprint printer with AirPrint Activator.
• Use Epson's app which seems to let you print black-and-white photos.
• Use HP's app which seems to let you choose these kind of settings.
• Tell Apple you want this feature.
