I want to print in B&W, but because the yellow ink is low (just low, not even out), it won't let me until I go out and buy unwanted yellow ink. This kind of manipulation into making customers buy more products than they need feels like bribery. Come on, play fair! I bought your printer, I bought your black ink, I just want to use what I have bought! Let it print! All that rubbish the marketing department spews out about 'our customers are important to us' is puffery. Canon's customers are treated with disrespect.
