Hi, I have just purchased a new printer Canon 3650 wireless Pixma.Struggling with how to connect with wi-fi,but have connected via a USB cable.Device manager on my desktop tells printer is ok.my question mainly is this? Why is there no program from which to select printing requirements ie,document,photos,scanning.the online manuel is not much help,so,I have the printer on,so how on earythe do I print something?
