Choose the Basic Settings tab. You have the option to change the duplex default: under 1-sided/2-sided/Booklet Printing:, choose 2-sided Printing. It is appropriate to set duplex as the default for all networked printers (unless an operator has specified otherwise), and for any other printer whose Comments textbox on the General tab ends with a notation that this printer should be set to duplex by default. (That choice was made by the printer operator.) For a few Canon MFDs, there will be dual queues: a BLDGRoom-CC5051 queue for color, and a BLDGRoom-Gray-CC5051 queue to either default to grayscale (b&w) printing, or even force it. You set this in the Printing Defaults on the Basic Settings tab, where Color Mode must be set to Black and White for a default-b&w or grayscale only queue.
