There are many different types of printers and scanners. They can be in different shapes and sizes and cost different amounts depending on the quality. Some of the types of printers are:

• Inkjet printer
• Laser printers
• Dot matrix printers

Inkjet printers are the most common printers at home. The use electrostatic spray technology which means that an ink cartridge goes forwards and backwards, spraying on the letters and pushing out the paper. It can print black and white or colour. The inkjet printer prints out 2 – 6 PPM( Pages Per Minute)

Laser printers are more commonly used in offices or other work places. They are a lot faster than the inkjet printers. They print out 8 – 200 PPM. Only one laser printer can print black and white and another printer can only print colour, there is no laser printer that holds both colour and black and white inside because the ink cartridge is too big.

The dot matrix printer has the most annoying sound any printer can make! It is an old version of a printer and the way it prints onto the is that a pin pushes onto a ribbon which pushes onto the paper and that’s what makes the words. The dot matrix printer can only print black and white, it cannot print colour.
