Yesterday, HP announced a new line of Web-connected printers that will allow you to print from any device with e-mail. If you're working on a document on your laptop, iPad, or smartphone, for example, you can send it to your printer's unique e-mail address to print it.  You also can print from a smartphone to a home, office, or public printer—at a hotel, say—using HP's' ePrint mobilie app. Another interesting feature: The printers allow you to schedule print jobs for designated times by registering for news or content feeds through the HP ePrintCenter. Prices start at $99 for the HP Photosmart e-All-in-One, which is expected to be available later this month. The rest of the line is slated to roll out in August and September.
