Summary: Bought it in 2005, if I recall correctly. It's now nearing the end of 2013. Connected to home network, so I can print from any machine in the house. The ink is replaceable, one color at a time, and without buying new print heads, so it's significantly cheaper to operate than most other inkjets. I bought it for the low cost per page, and have been very satisfied with that. And, well, all these years later, it still prints fine!
Summary: I bought this Canon iP4000 printer because it has the following attributes: 1. It has five ink cartridges, BCI-6 BK, M, C, Y & BCI-3EBK which are easy to refill - they are transparent and have no chips. 2. The ink cartridges stand alone and share a common, replaceable print head. 3. The canon purge unit is better than any other ink-jet printer of similar vintage. 4. It is capable of printing on CDs & DVDs if equipped with a CD Tray. 5.
Summary: We had this printer for MAYBE two years when it just "stopped" working. It was a great printer while it lived. It did seem to got through a lot of ink, more than any other printer we've had. Anyway, as much as I loved the printer... there is no way I'd pay $325 for it (price when I posted this-4/12/08). I bought it for $209 in 2005. I don't think I'd spend $150 on it today. You could buy better pinters now for less.
Summary: I have used printers from most of the major manufacturers. I got fed up with HP inkjets and switched to canon a couple years ago. My first Canon was an iP4000. The photo quality is amazing (the best I've seen in this price range by far), the prints are fast, it can feed from two different trays, and it can print on small photo paper borderlessly.
Summary: I finally upgraded from an ancient (but still working) CanonBJ, and I'm very happy with the results. Setup, including connecting through my wireless router, was a breeze; printing is speedy whether through my desktop or laptop; photo quality is great. Letter-size paper in the top feed and photos/envelopes in the tray offers good flexibility. I had trouble installing the Canon "Easy Web Print" on my laptop for some reason, but it isn't an essential feature.
Summary: The unpackaging and ink cartridge instructions are concise and easy to follow. Pop the Pixmaip CD into your PC and follow the directions to install the printer on your wired or wireless LAN. You'll also automatically install the printer drivers, setup the printer device on your PC and load software useful for picture viewing and editing. Printer setup was a no-brainer and thus far the Pixma ip400R has been totally print reliable.
Summary: I have a home network with both Windows XP and Mac OSX computers - 1 Windows desktop, 1 Windows laptop, 1 iBook. I struggled for a year trying to get my iBook to print on the printer attached to the desktop. I also tried several print servers, and never managed to get a good network printing solution. Then, I happened upon the Canon iP4000R.
Summary: This is one amazing printer. The print quality is outstanding. Photos look professional, they look exactly the same as photo-lab prints. Black text looks laser quality and the WiFi feature lets me print from anywhere in my house, from any one of my computers.
