I ordered this 4300 for the office on the basis of great results with its predecessor, the 4200, at home. If you're new to the Pixma line, expect the machine to function flawlessly if not beyond expectations, though at a slightly higher cost in ink than other printers. (Always keep a spare of each of the 5 colors on hand, and forget about finding clones for this model or cheaper ink prices than those posted on Amazon.) The iP4300 is a slight upgrade of the extremely popular iP4200 (see reviews of that machine). If you print a lot of photos, you'll notice a 40% increase in the rate of processing. If you want a preview monitor on your printer, you'll find it available on the higher-numbered, costlier Canon Pixmas (the ip6600 is the newest; the price of the ip6000 is currently attractive, but the machine is two years old). Finally, I wouldn't discount the duplex printing feature, retained on the 4300. It has saved me not only paper but numerous trips to the copy machine.
Advantage of the iP4300 over the 4200: Significantly faster printing of color copy because of added ink jets.
Disadvantage of IP4300: Slightly wider and deeper than the 4200, taking up more desk space. (Height and weight are the same.)
Bottom line: Still the best and most dependable all-around printer (not just photos) for home or office in this price range, at least until HP or Epson (I've previously owned both) return to form. If you need a clincher, it's the duplex printing.
