Canon's new wide-format entry is the most affordable photo-quality alternative for those of us who want a printer that produces 17-inch-wide output and also offers roll-paper capability. With its 12 Lucia inks and simultaneous blacks, the Canon imagePROGRAF iPF5100 combines very high image quality with an important convenience feature -- the ability to switch, on demand, from glossy to matte black ink, and therefore from glossy to matte paper -- that is lacking in the Epson Stylus Pro 4880. And due to newly tweaked black inks, its monochrome output is excellent, with no visible bronzing on glossy paper, better scratch resistance, and little apparent color shift under different light sources. The iPF5100 is also much improved over its predecessor, the iPF5000, in its user interface (friendlier) and documentation (more thorough). There are trade-offs: You can get larger, 220ml cartridges for the new Epson SP4880, while the iPF5100 only accepts a single 130ml size. But unlike the SP4880, the Canon features automatic head checking and cleaning. And its dual print head speeds output by reducing the number of 'passes' needed to complete a print.
