"Little photo printers are becoming all the rage. Forget iPods, 3G mobile phones and paper light laptops because printers have never been so trendy. The run up to Christmas has seen them splattered all over your television screens, magazine pages and even onto the side of the odd bus or two. Yes, it seems we have finally hit the sweet spot where everyone can afford a digital camera and the race to offer Joe Blogs a cheap and convenient printing solution that Mrs Blogs (or vice versa of course) can wrap up and slip under the Christmas Tree, is on. Everyone from Canon to Sony is crying out for us to dip into our wallets, but the mass market specialists are obviously Epson and hp. A few months ago we tested and loved Epson’s PictureMate and found it to be a great solution for turning your digital photos into tangible prints, so the pressure is on hp to pull something equally good out of the hat."I've often thought about getting a mobile printer, specifically for family events where I want to produce prints instantly, but I'm not entirely sure it would be worth the investment. Any owners of mobile printers here? How do you use them?
