My Brother HL-3040CN printer only has an ethernet connector for network printing (as well as a usb port). If I wish to print wirelessly is there an adaptor or a wireless hub that I can plug it into with the cable? I'm asking this because I've read the iPad doesn't have any means of connecting it to a printer with a cable. I won't buy an iPad now but maybe next year. Thanks EDIT: Would an Airport Express do the job?
