Most printers come with a variety of fonts built into their RAM , and those fonts can be scaled up or down in size without losing quality. Your printer will also download software-based typefaces automatically from your computer. Virtually any graphics program will install dozens more on your system, and if that isn't enough, your local software retailer can sell you disks with dozens of decorative typefaces for a few dollars. By laying down dots in a different way, your printer can produce graphic images. Better printers can produce finer, more detailed images with fewer jagged edges than those printed by less-capable machines.
Color printers can add visual impact to almost any job.
They mix colors from cartridges containing cyan, magenta, yellow and black ink using the same principle artists use when they mix paints of different colors on their palettes.
