Query: Excellent Wi-fi Printer

I purchased this printer for the wi-fi feature. I did not have any problems setting this up on my network and it was quick. The 4550 replaces a Canon i860, that I was very happy with but as other reviewers explained you needed your computer on to use over the network. This also replaces a U-Max scanner. I agree with most on the ink being more expensive due to not being able to use refillable cartridges. That is why I give it four stars.
