- A printer is peripheral which prints the graphics or text on the paper or similar physical media.
- A printer has ink in the cartridge and uses that for printing whether color or black and white based on cartridge used.
Types of Printers:
1.Laser printer:
- A laser printer rapidly produces high quality text and graphics.
- As with digital photocopiers and multi-function printers (MFPs), laser printers employ a xerographic printing process but differ from analog photocopiers.
- In that the image is produced by the direct scanning of a laser beam across the printer's photo-receptor.
2.Inkjet printer:
- Inkjet printer is a type of printer that produce the image by propelling the droplets of ink on paper, plastic and other materials used for printing.
- It is widely used printer in house hold and organisations.
- Its range from small inexpensive consumer models to expensive professional machines.
3.Thermal Printer:
- Thermal printers work by selectively heating regions of special heat-sensitive paper.
- Monochrome thermal printers are used in cash registers, ATM, gasoline dispensers and some older inexpensive fax machines.
- Colors can be achieved with special papers and different temperatures and heating rates for different colors.
- These colored sheets are not required in black-and-white output. One example is Zink (a quality of "zero ink").
4.Plotter:
- The plotter is a computer printer for printing vector graphics.
- In the past, plotters were used in applications such as computer-aided design, though they have generally been replaced with wide-format conventional printers.
- A plotter gives a hard copy of the output. It draws pictures on a paper using a pen. Plotters are used to print designs of ships and machines, plans for buildings and so on.
