Summary: I have used this printer for a little over 6 months and have absolutely no complaints. I started out using the Canon inks, but have recently used generic ink tanks, with no change in print quality or printing problems. I use it in an office environment, and it gets used a lot. We are looking at replacing all our old HP and Epson printers with these since they are very affordable and the ink cartridges can be had for $3-5 each, versus the expensive HP tanks.
Summary: When my laser printer broke, I decided to try an inkjet because there were times when I would have liked to have color printing. Based on research and reviews, I picked the Canon PIXMA iP4000 Photo Printer. It seems odd that it's called a "photo printer," because in addition to photos, it prints everything else. I love this printer! It is quick, quiet, and the printing is high quality. It was an added surprise to discover that it prints duplex.
Summary: The printer is easy to set up and use. I like the fact that I can completely close the printer case between uses(no need of dust cover). I primarily print text, but feel the photo quality is excellent compared to my old HP 692C. A very fast printer as well. I have not yet printed using photo paper. Best feature of this printer is cost per page. Far cheaper then any other printer.
Summary: This printer is the quietest printer I've ever used, very easy to setup,I had mine out of the box and running in approx. 7 minutes! The ip4000 has amazing photo quality, at an amazing speed to boot!
