Upside: The Pixma iP4000 garnered decent scores for its fast performance, its high paper-input capacity, its convenient dual paper trays, and its reasonable print quality. We expect the same out of the iP4000R. The only thing that distinguishes this printer from its step-down model is its networking capabilities; it supports Ethernet, 802.11b, and 802.11g for convenient home networking. Also, like the Pixma iP4000, the iP4000R is priced very competitively.
Downside: For the money, the prints are good, but if you're the type who wears a loupe around your neck, you'll probably be disappointed with the photos. The Pixma iP4000R will have the same print issues as the iP4000: feathering around the letters in text documents, as well as dithering and banding in photos.
Outlook: Decent output, networking options, and fast print times should put this Canon ($229.99 list) near the top of its category. We'll let you know for sure when it ships this fall.
