Summary: The iP4500 produces very high quality printing and photos. It was one of the easiest systems to refill ever produced. It is MANDATORY to use high quality inks and understand that you cannot refill a cartridge indefinitely. Chip resetters are available and reasonable on eBay. Not all aftermarket cartridges are as easy to refill and reset as the Canon products. The price of this printer has climbed, since Canon stopped production.
Summary: My last printer was a Canon i960, which I thought at the time was the last word in performance for around $100, and it truly was. It had 6 ink cartridges, and a miniscule 2 picolitre droplet size -- and rendered the best and fastest photos I'd ever printed (4x6 in 34 seconds). But I made the mistake of buying cheaper ink replacement cartridges, and not using the printer regularly.
Summary: I purchased the Canon Pixma iP4500 inkjet printer to replace an old Canon i850 color inkjet printer. The old printer worked great for a few years, then stopped working properly even though I used only Canon ink cartridges. So far the iP4500 seems to print text and photos very well - actually better than the old printer. I am hoping it lasts longer than the i850. The ink cartridges are very easy to change.
