In tests, we experienced nary a paper-handling problem with the i550, even when we fed it poor-grade, curled-edge paper that would choke a lesser printer. Even paper outages caused no more than a wrinkle in the process. A clear notice from the included setup CD guides you through the paper-loading process, and printing resumes when you hit the printer's reset button--one of only two on the printer.

Like other new Canon printers, including the S820D, the i550's ink cartridge contains four separate tanks: one each for black, cyan, magenta, and yellow (called the Think Tank System). While the ink-changing process is a tad cumbersome, this model is cost-effective for color printing. You needn't throw out leftover yellow and red ink when you run out of blue, for example. Replacement BCI-3e tanks retail for less than $10 apiece for three-color cartridges, while black ink will run you $10, all of which add up to a low cost per page. In our heavy-print tests (which assume a 50 percent ink coverage on the page), pages came in at just more than 3 cents for black printing and 19 cents for color. That lands the i550 among CNET's top 10 printers with lowest per-page print costs, alongside the ancient HP 2250tn, the Lexmark J110, and a mess of other Canon printers.

But although the i550 saves you cash, it boosts your labor quotient. Because you don't replace it every time you change ink cartridges, the printhead will have to be cleaned often--a noisy process for a printer that's pretty loud to begin with.
If you are a gambling type, bet on the i550 to place rather than win the speed race. Although this printer makes quite a racket while running, it's not quite fast enough to beat the current print-speed frontrunner (the Canon S9000 Photo still outpaces it in both text and photographic output), but it does come in ahead of the pack. In our tests, the i550 spat out a page of text in less six seconds (barely trailing the Lexmark Z45 in text and beating its photo speeds by nearly 2 minutes per page).
When it comes to images, the i550 is also a mixed bag. The printer supports EXIF printing, which improves prints from EXIF-enabled digital cameras. (EXIF data embedded in JPEG files provides camera setting data to optimize print settings, which is great if you have an EXIF digital camera but extraneous if you don't.) But with our non-EXIF files, the 8x10-inch photo looked grainy and streaky, trailing output from the entire Epson Stylus line.
