Epson has announced the mobile WF-100 printer, and at 3.5 lbs it claims to be the smallest and lightest printer on the market. Along with portability it boasts printing from mobile devices by way of built-in Wi-Fi and Wi-Fi Direct for peer-to-peer connections, and offers borderless 4x6 photo printing. The WF100 is powered by a rechargeable lithium-ion battery and can charged via USB or the included AC adapter.

The printer works with quick-dry inks which create water and fade resistant prints. It will be available through online retailers in early November and in retail stores in January 2015 for $349. Find out more at Epson's website.
