Can anyone recommend a multifunction machine that allows me to use automatic answer with a distinctive ring in the fax and duplexing (printing on both sides of the paper) in the printer? Or, can you recommend a site where I can find the data. I've checked a couple of sites that list a variety of printer,fax,scanner,copier machines but none provide the necessary information. I now find that Windows XP doesn't support the features I need (distinctive ring and duplexing).
