At this week’s Macworld Expo, HP (http://www.hp.com) has expanded its HP Officejet portfolio with a new flatbed all-in-one printer: the HP Officejet 4500 All-in-One. The company also announced the worldwide availability of the HP Creative Studio for Business, an online resource to help customers grow and market their small businesses.

The HP Officejet 4500 All-in-One series starts at US$99, features a piano-black finish and a 20-sheet automatic document feeder. The Mac OS X 10.6 (“Snow Leopard”) and Windows compatible all-in-one offers borderless printing for brochures, flyers and other documents, built-in Ethernet and wireless networking options.

In addition, it produces fast-drying documents that resist fading when using papers with the ColorLok logo. With the optional HP 901XL Black Officejet Inkjet Cartridge, small businesses can now print up to three times more black pages for greater savings, according to the folks at HP.

As part of the HP Eco Solutions program, the Energy Star qualified HP Officejet 4500 All-in-One series conserves resources with HP Smart Web Printing. The HP Officejet 4500 All-in-One and HP Officejet 4500 Wireless All-in-One are expected to be available for purchase worldwide next month.
