Printers A printer can be defined as a device that accepts text and graphic output from a computer and transfers the information to paper, usually to standard size sheets of paper. Printers are sometimes sold with computers, but more frequently are purchased separately.
Printers vary in size, speed, sophistication, and cost.
Larger laser, for example, can print a 400-page manual in a few minutes. Personal computer printers print only a few pages a minute. Personal computer printers can be distinguished as dot-matrix , inkjet and laser . Impact dot-matrix printers work by striking a series of dots through a ribbon for each p rinted character. The dot-mat rix printer is still popular in businesses that use carbon copy forms.
