Dot-Matrix Printer.
It is a character printer that prints one character at a time. This Printer can form characters and all kinds of images as a pattern of dots. Since dot matrix printer produces printed output as a pattern of dots, they can print any shape of a character that a program can describe. They, therefore, can print many unique traits, different sizes of print, and also have the ability to print graphics such as charts and graphs.
Dot Matrix printer is usually haves slow printing speeds ranging from 30-600 characters per second. They are available at little cost. These types of printers are used to print the shipping invoices.
Inkjet Printers.
It prints characters by spraying patterns of ink on the paper from a nozzle or jet that can heat up selectively. The ink comes out of the nozzle in the form of vapors. After passing through a reflecting plate, it creates the desired letter/shape at the place you want. It is also a Character printer, but it produces high-quality output than dot matrix printers because these printers form characters with very tiny ink dots. Printer and Its Types.
Inkjet printers are slower than dot matrix printer as inkjet printing speed is 40- 300 characters per second. An inkjet printer is also more expensive than dot matrix because it produces the high-quality prints with more transformed technology. These printers are very popular because they are cheaper than laser printers and can print faster and accurate than dot matrix and other impact printers.

Drum Printer.
Drum printer is a line printer that prints one line at a time. Also, the drum printer is also the impact printer. In this Printer, it has a set of hammers mounted in front of the drum in a manner that an inked ribbon and paper can be placed between the sticks and the drum. Then the drum rotates at high speed. A character is printed at the desired print position.
This printer has the speed of 300- 2000 lines per minute. This printer also produces lots of noise that’s why the cover is used to reduce the noise. Printer and Its Types.
Chain Band Printer.
Chain/Band printer are line printers that print one line at a time. It consists of a metallic chain/group on which all characters of the character set supported by the printer are embossed. A standard character set may have 48,64 and 96 characters. The characters in the character set are embossed several times on the chain/band.
Unlike drum printer, the chain/group printer can be changed quickly. It allows the printing to be done in different fonts and styles in the same printer. Due to the impact printing chain/band printers are noisy in operation and often use a cover to reduce the noise level. Printing speeds of the chain/band printers range from 400 – 3000 lines per minute.
Laser Printers.
Laser printers are the page printers that prints one page at a time. The main component of the laser printer is a laser beam source, multi sided mirror, a photoconductive drum, and toner. Laser printers produce high-quality output because they form characters by very tiny ink particles. The high-end laser printer can have a resolution of 1200 dpi. Due to the high resolution, these printers give excellent graphics art quality. Printer and Its Types.
Laser printers are faster than other printers discussed earlier. Low-speed laser printers can print 4 to 12 pages per minute. Owing to their better print quality and printing speed, laser printers are more expensive than the other types of the printers. These printers are very popular in the market because of its fast printing.
