Canon Pixma MG542 b/w printing from iPad

[ghostdog]

I have not been able to select "black and white" printing from my iPad Air, although I am able to do so from my Mac Book. 

Any suggestions?

Hi ghostdog,

Printing features are limited to what the app you are using provides.  If the app you are using does not offer black and white as an option, then you would not be able to print black and white with your PIXMA MG5420 from that app.
