Summary: I bought two of the 4500s in 2006 or 2007. I have been using one of them as my everyday workhorse. I replaced the printhead recently (March 2013). I bought these printers through the Canon store for around 100.00, maybe 99.00. It was cheap. I print photo cards- sometimes as many as 100 a day and this printer has never failed and it's good on ink so prints are cheap to make. I've used cheaper non OEM ink that is a fraction of the Canon ink with no ill effects at all-ever.
Summary: This printer at first had "the goods", it was quite fast, printed excellent photos, printed off my band cds with ease and high quality documents. Sure it used ink slightly faster than I would have liked and it also didn't let me print black and white if one of the colour cartridges was out (and no, there is no bypass code on this one) but I got used to that. So why the two stars? The other day, after working fine the night before, it just refused to turn on. At all.
Summary: Very reliable, trouble-free on my Mac Pro system. After some bad experiences with third-party cartridges and Epson printers, I changed brands and learned to stick with genuine brand ink. Third-party inks tend to clog print heads, and the design of Epson inkjet printers is highly prone to clogging.
Canon printers would be great if they were reliable

Summary: I bought this printer a few years ago to replace a more expensive Canon printer that had given up the ghost. (That first Canon, which set me back $400 and used 8 ink cartridges, printed *gorgeous* photographs -- which is why I bought it -- for a little over 3 years, when its warranty ran out and I found one day that pressing the power button no longer turned it on. I took it to a Canon service center and was told it would cost $200 to fix.
Won't print in black and white if color ink is out

Summary: Disaster as a point of sale printer since if say the yellow is out you can't continue to print your invoices! Doesn't matter if you select grayscale in the properties. It will refuse to print period... Cruel joke of a printer.
Summary: Like many on here I purchased this based on reviews and previous experiences with Canon. I'm beginning to regret it as the constant replacing of ink cartridges is getting to be a real pain. As others have pointed out, when one color runs out there is no way of printing in black and white. You either have all the cartridges functional or the thing will not print, in essence making it a really expensive paperweight until you get some more ink.
Summary: When you run out of color ink, it won't even allow you to print in black and white. Why? So that you constantly have to be purchasing every single ink-tank (spending more money, even if you don't need the color ink) in order to have a functional printer. I want to print out a standard black and white letter, but cannot since the "magenta" cartridge is out. Even with grayscale as the preset, there is no way around this...
