Uhh, i've never seen a single-catridge inkjet...how does this work? You can either print all B&W or color only?

The very first color inkjet printers, such as the HP DeskJet 500C, were single-cartridge printers...you replaced the black cartridge with a color cartridge. 3-ink process color mixes cyan, magenta, and yellow inks to produce something that approximates black. On plain paper, the approximation was usually not that great, and (as already noted) since all three inks are needed for grays and black, a single-cartridge inkjet printer will suck down color cartridges like there's no tomorrow. When dual-cartridge printers were introduced, the single-cartridge printers hung around for a while as "economy-model" color printers. They had all but disappeared a couple or three years ago, as dual-cartridge printers had gotten cheap enough for everybody. Why Lexmark has brought back the idea is anybody's guess, especially since I think the last single-cartridge printer they built was the Medley multifunction printer back in '95 (if that gives you an idea how old this tech really is, and even the Medley is hardly the oldest).
