12. PRINTER
- It is a computer device that produces a permanent copy on paper of information from the computer. There are several kinds of printers: ink jet, dot-matrix and laser jet printers.

13. DOT MATRIX PRINTER
- Prints by hammering or striking an ink-soaked cloth ribbon against a paper. The advantage of this kind of printer is that it can easily create carbon copies because of the impact action of the printing process. The cost per page of printing is relatively cheap.

15. INK JET PRINTER
- Operates by propelling or spraying different sizes of very small and precise amount of ink onto a paper or other media. Printing quality of this printer is better than the dot matrix.

16. INK JET PRINTER
- The ink comes form a cartridge of liquid ink and this printer is simply black and white or in full color.

17. I N K J E T

18. LASER JET PRINTER
- It produces high quality prints or graphics on paper. Color and black and white printing is available. It is based on the principle of electrostatic printing and photography wherein the source of ink is a toner.

20. PLOTTER
- It comes in 2 types: pen plotter and electrostatic. Pen plotter is a vector graphics printing device which operates by moving a pen over the surface of paper.

21. PLOTTER
- It is usually used for large printing requirements of CAD drawings of houses, buildings, cars, airplanes and others. It is also used for vinyl and plastic used for billions and posters.

23. THERMAL PRINTERS
- Produce prints on thermal paper by selective heating wherein heated areas turns black creating an image. It is mostly used in groceries and department stores. They print faster and quieter than dot matrix.
