HP just announced their new HP Photosmart Premium with TouchSmart Web, which has a web-connected touchpanel on the front, allowing you to print out content such as maps and coupons, straight from your printer.
The TouchSmart Web UI has a widescreen panel about 4" in size which has a series of thumbnails that you flick through to access web content. In addition, the printer will come with an open API, letting any web content developer create widgets for the printer.
Showing off content demos from partners such as Google, Snapfish, Fandango and USA Today, HP is convinced this will "revolutionize" and "change the way people think about printing." While that remains to be seen, we do know the printer itself is wi-fi enabled, can copy/scan/fax and will cost $399.
