Non-impact : Laser printer
-- It is type of non impact printer.
-- This printer works like a photocopy machine.
-- Using pattern of small dots, a laser beam transfers information from the computer to a positively charged drum.
-- The toner ( ink powder) detaches from all those areas of the drum that becomes neutralized.
-- As the paper rolls by the drum, the toner (ink powder) is transferred to the paper, printing the letters or other graphics on the paper.
-- A hot roller bonds the toner to the paper.
-- It prints the whole page at a time.
-- Depending on the model, it either can print in colour or black and white.
-- A laser printer costs more than an inkjet printer but the running cost ( toner cost per page ) is much lower.

Non-impact : Inkjet printers
-- Inkjet printers work in the same fashion as dot-matrix printer, however here, the dots are formed by tiny droplets of ink
-- inkjet printers from character on paper by spraying ink from tiny nozzels through an electrical field that arranges the charged particles into characters at the rate of approximately 250 characters per second (cps).
-- The ink is absorbed into the paper and dries instantly. Inkjet printers can print in colours too.
-- Ink cartridge per page costs is much higher than that of a Laser printer.

Impact printer : line printer
-- It is a type of impact printer.
-- Where enormous amount of material is to be printed, users need line printers.
-- Line printer, or line-at-a-time printers , used a special mechanism that can print a whole line at once.
-- They can print the range of 1,200 to 6,000 lines per minute(Ipm).Drum, Chain and band printers are line-at-a-time printers.

Impact printer :- Dot Matrix Printer
Dot Matrix printer is an example of impact printer which print text on paper by using ting dots to form desired character.
-- It uses an array of metal pins known as print head to strike an inked printer ribbon and produce dots on paper.
--It prints with a speed of 100 to 600 character per second (cps).
-- The number of pins used in print heads varies from 9 to 24 .
-- It can print only in black and white.

Impact printer :- Where there is a physical contact between the print head, ribbon or cartridge and paper ( media).
Non- impact printer :- Where there is no physical contact between the print head, cartridge and paper( media).
