WE 21st century techies love our iPhones, MP3 players and notebook computers. Oddly, printers have never quite won our favor. In fact, if there is one device that we love to hate, it is the office printer, which always seems to get a paper jam at the most inopportune times. Now computer companies are trying to sex up their printers in hopes that we will finally start to fall in love with them, too.
