Packard on Wednesday added mobile printing to its enterprise services offerings, giving BlackBerry users a new way to print documents on the go. A new services offering called ePrint will let BlackBerry users securely print documents from printers at public locations like hotels, airports or libraries, said John Tomesco, vice president of marketing and development for HP's Imaging and Printing Group. Users will be able to print e-mail messages, images, presentations and documents in file formats such as PDF. HP is providing an ePrint application for BlackBerry smartphones to locate and select the closest printer, after which users can finalize printing of the document. An e-mail with a security code is sent that authorizes printing of the document. Users need to reach the print and punch in the code, after which the document is printed. Users will need a BlackBerry smartphone OS 4.5 or newer and a wireless Internet service to use the service. To enable the service, HP is partnering with PrinterOn, a company that maintains a network of thousands of printers in locations like cafes, airports, libraries and hotels.
