A printer outputs data that is seen on the computer screen. Most printers are used through a parallel port, but some newer ones use USB connections. USB is somewhat faster, but there's not much of a difference for printers. Networked computers usually print to a printer through the network card. The most crucial printer measurement is its dots per inch rating. Although this can be misleading, a higher number is generally better. Printers are best chosen by actually seeing the quality of the printer output.
A device for printing results from your computer on paper or other "hard" media. While there are many kinds of printers, most these days fall into two groups. Inkjet printers use a technique to "spray" the ink onto your paper. Practically all inkjet printers these days can print in color, and can print from 2 to 12 pages per minute. Laser printers use a combination of copier technology tied with a laser to essentially "copy" the image onto the paper. While color laser printers are available, they are expensive. Laser printers can print from 15 to 50 pages per minute
