5. Dot matrix printer The term Dot matrix refers to the process of using dots to form an image. In a dot matrix image, the image quality is determined by the number of dots per inch A dot matrix printer creates characters by striking pins against ink ribbons. Each pin makes a dot and combinations of dots form characters and illustrations. This is much like a typewriter Dot matrix do not provide high quality output

6. The speed of dot matrix printer is measured by the number of character it can print in one second . The speed of most dot Matrix printers ranges from 350 to 1100 characters per second

7. Line printer Line printer is type of impact printer. It is fast impact printer. It print an entire line at a time. Its speed measured in line per minute. They can Print 300 to 3000 Lines per Minute.

8. Type of Line printer Band printer Band printer print characters by striking hammers on a rotating horizontal band Chain printer chain printer is similar to band printer. It contains complete set of characters on several sections of a chain. The chain rotates at high speed
