Picked this up from CNN, Polaroid just debuted their new tiny printer at the recent CES 2008 and guess what no ink required because they employ a thermal printing technology from startup Zink Imaging Inc.
You can see from the picture above that its tiny printer almost the size of a regular mobile phone and it will be retailed at about $150. Once connected to a phone or camera by Bluetooth wireless or the USB port, the printers need less than a minute to churn out 2-inch-by-3-inch pictures, which can be peeled off a backing and used as stickers. Sheets of paper for the device will cost about 40 cents each, less if bought in bulk.
I m not surprise that someday the printer will be integrated with the mobile phone. All you need to do is to snap a picture or open up a PDF file and out it comes into a hard copy from the mobile phone.
