Say you what you want about wasting paper and physical prints, but there’s still a necessity for physical documents, and Hewlett Packard is unveiling their ePrint service for the iPhone so you can print and pick up documents from just about anywhere (previously only available on Blackberry). Compatible with HP AirPrint printers, or via a registered public ePrint location, you can print documents on the fly using your iPhone and pick up your papers at a local printer, whether it be at home or at your hotel’s front desk. At public locations, your prints can be collected only with a retrieval code at a pickup desk (FedEx has 1,800 locations for ePrint). I don’t know how much you want to trust the person behind the counter, but for printing a map or getting a hard copy of a local flyer, it’s certainly a nice option to have. For enterprise users, you can print to your private-cloud so you’ll have your documents as you return to your desk (HP advertises their ePrint Enterprise Solution separately). HP’s ePrint is a free download in the App Store.
