It works the same with black and white, but you only have to sample for luminance instead of intensity of three primary colors. So a third as many bits as a color scan is what you're usually going to get from current scanners in B&W mode. IOW, if the scanner does 24-bit color (eight bits each for red, green, and blue) it will typically do eight-bit grey scale. For high-quality B&W work you probably want a scanner capable of 12-bit B&W (36-bit color). The extra bits will make for a _lot_ less banding of adjacent, subtly different grey shades.
