The Pixma iX6550 looks the part of a multifunction printer, but this is solely a printing device, not a scanner, fax or photocopier. What it does hide within its body is a deceptively small A3 printer. That's not to say that the Pixma iX6550 is particularly tiny; at 549x299x159mm this is still a large printer. It's just that compared to most A3 printers, however, it's small for what it does.
The finish is in glossy piano black, which naturally means that even unpacking the Pixma iX6550 makes it look something like a recently dusted crime scene, awash with fingerprints. It's a relatively hollow printer (as most printer bodies are), but the increased size of the Pixma iX6550 exacerbates this, and makes actions like flipping up the paper tray reverberate with a hollow and cheap plastic sound.
The Pixma iX6550 is, as noted, an A3 colour inkjet printer with a surprisingly simple feature set. There's no multifunction ability, there's no card or USB reading facility. There's no networking on board, be it cabled Ethernet or Wi-Fi. This is a USB-only connected printer, and for those small offices that need a networked A3 printer for, say, proofing purposes, this has implications, as you'll have to leave it tethered to an always-on PC or Mac in order to share its printing abilities.
The other office supply you'll need to pinch to get the Pixma iX6550 working is a USB cable. If you're moving from another printer chances are that you'll have a cable handy, but if not, it's worth noting that your AU$399 doesn't extend to Canon supplying you with a cable in the box. Given it's required for set-up, it's a particularly irksome omission.
