In a flurry of product announcements from Shanghai, HP introduced one new All-in-One (AIO) printer, a replacement for the current 5510 called the 5520 that addresses all the significant omissions of the previous model, mainly the duplexing and layout support. The 5520 e-All-in-One features a new automatic duplexer for easy two-sided support, along with options for booklet and multi-page printing. Wireless mobile printing is also supported.
