What is a Non-impact printer ? Explain the types of Non-impact Printers.
Non-impact printer
A non-impact printer prints characters and graphics on a piece of paper without striking the paper. Some of these printers use spray ink while others use heat and pressure to create images. These printers are faster than impact printers.
Types of Non-Impact Printers
Different types of non-impact printers are as follows:
- Laser printer
- Inkjet printer, and
- Thermal printer
Laser Printer
Laser stands for light amplification by stimulated emission of radiation. The laser printer is a non-impact printer. Its working is similar to photocopying machine. It uses laser beams to burn special powder on page to create a permanent image. The power is contained in toner. Laser printer prints complete page at a time. It is also known as page printer.
Inkjet Printer
An ink-jet printer is a type of non-impact printer. It prints characters and graphics by spraying tiny drops of liquid ink on paper. These printers can produce quality text and graphics in both black-and-white and color including photos. A typical inkjet printer provides resolution of 300 dots per inch. The latest inkjet printers provide higher resolution.
Thermal Printer
Thermal printer uses color waxes and heat to produce images on special paper. The color wax sheets are not required for black-and-white output. Thermal printers are expensive and require costly paper. These printers are used to create the highest-quality color printing.
