Question: what is the difference between hp sprocket and hp sprocket 2nd edition?
Answer: A Quirky, Spiffy Printer Because the HP Sprocket Plus ($149.99 at HP) prints slightly larger photos than the original Sprocket and the Sprocket 2nd Edition (the pics are 2.3 by 3.4 inches, versus the more common 2 by 3 inches), the Sprocket Plus is slightly wider than the other two.
