Summary: I bought the Canon i550 used, open box, to replace my 7 year old i350. it worked fine after I bought a couple of ink tanks that were low. I picked the i550 because of the reasonable ink prices, and it will take generic cartridges. Printing is quiet, bold (on HQ setting), sharp, and with about average speed, or a little better.
Summary: I absolutely love this printer. My husband and I first bought it in 2002 in Japan. When we left the country, we took this printer with us. After traveling over 7000 miles, it is still able to print paper after paper. It also prints great pictures. I still prints like new.
Summary: I have been through 2 of these printers over 3 years..yes seems like a lot but i have never paid more than 50 dollars for it. The price of the ink makes it a bargain. Sure I could go buy an Epson or a better Canon but the ink alone makes it expensive for these more expensive printers. I even tossed out the "freebie" Epson printer that I got with my computer, because the printer ink alone was just outrageously over priced.
Summary: I really like the Canon printers primarily because of the separate ink cartridges for each color. The 550 Model uses the fairly large 3e ink cartridge so you don't have to change cartridges very often. I purchased the i550 because I have one already and wanted the second printer to use the same ink. The print quality of the i550 is good for a home printer.
Summary: When I bought a laptop I decided to get a printer for it. I had one of these printers on my desktop and have used it for everything from ordinary text to printing photos. I have always used Canon printers for digital printing at my job or home printing. Since I had one it made sense to buy another so that I could use the same inks in both and also knew how dependable it is.
Summary: loved the menu loved the fact that refills were only a buck a pop and easy to get from wholesalers loved the fact that each color was in a separate cartridge so that you are not harrassed to buy new refills every time you end a color demanding print job! lightweight portable design fit comfortably under my desk but got old and i did not clean/maintain it often enough so it slowly halted... wish it was cheaper to fix than to buy new...
