From Canon website:
This compact photo printer delivers true ease of use and amazing results. Its patented print head technology lets you produce beautiful, long-lasting photos with borderless edges, from credit- card size, up to 8.5" x 11", and with resolution up to 4800 x 1200 color dpi1. It's fast, too: A superb 4" x 6" borderless print takes only about 55 seconds2. For better results, the Auto Image Fix feature automatically corrects images for the best possible exposure, color, brightness and contrast. Also, the specially formulated pigment black ink delivers clear, laser-quality text with better readability and a higher resistance to smudging.
