I found these steps in the knowledgebase on the setup procedure for Wifi that my help you get printing.
I can't figure out how to print using WiFi from my Macintosh to the B210. I am beginning to think it is impossible. The wifi technician could make it print either. Using a USB cable it prints but the desire is to place it in another room not tether it by cable.
Instructions on the web are difficult to understand.
