Hi, I am completely confounded and frustrated by this problem. I have a macbook. Our wireless internet connection is set up on a network and router through my boyfriend's PC computer. We are trying to set up a connection so that I can print wirelessly to his printer, through the network and printer sharing (which is enabled, by the way). The printer I'm trying to use is a Canon PIXMA MP960. Nothing seems to work. I have had no problems in the past printing wirelessly to printers hooked up through my own apple airport router. But I cannot seem to see, add or connect any printer through his windows/PC network. ?? Any help???
