A printer is an output device that prints text and graphics on paper. There are two main types of printers - impact printers and non-impact printers. Impact printers work like typewriters using pins or hammers to strike ink ribbons and transfer ink to paper, while non-impact printers use technologies like lasers and inkjets that print without physically striking the paper. Non-impact printers are generally faster, quieter and provide higher quality output than impact printers.

1. “A printer is an output device that prints characters,
symbols and graphics On paper. The printer output
is called hard copy. Printer resolution is commonly
Measured in dots per inch”
"A printer is an external output device that takes
data from a computer and generates output in the
form of graphics / text on a paper".

5. 
An impact printer works like a typewriter .
It prints characters or images by striking a
print hammer or set of pins against an inked
ribbon
The ink is pressed from the ribbon on the
paper to produce the output
Impact Printer

6. Impact printer are the oldest print technologies
Which are still produced the impact printer are
used where low cast printing is required there
most common from of impact printers are dot
matrix printer, daisy wheel printer and line printer

7. Dot matrix printer
The term Dot matrix refers to the process of
using dots to form an image. In a dot matrix
image, the image quality is determined by the
number of dots per inch
A dot matrix printer creates characters by
striking pins against ink ribbons. Each pin
makes a dot and combinations of dots form
characters and illustrations.This is much like a
typewriter Dot matrix do not provide high
quality output

8. The speed of dot matrix printer is
measured by the number of character it
can print in one second . The speed of
most dot
Matrix printers ranges from 350
to 1100 characters per second

9. Line printer is type of
impact printer. It is fast
impact printer. It print an
entire line at a time. Its
speed measured in line
per minute. They can Print
300 to 3000 Lines per
Minute.

10. Band printer
Band printer print characters by
striking hammers on a rotating horizontal band
Chain printer
chain printer is similar to band
printer. It contains complete set of characters on
several sections of a chain.The chain rotates at
high speed

11. Daisy wheel printer
Daisy wheel printing is an impact printing
technology invented in 1969. It is similar to a
typewriter. It uses a print wheel.The print
wheel is daisy wheel

12. A motor rotates the wheel. A hammer strikes a petal
against the ribbon when the desired character reaches
the position
on the paper. This
prints the character
on the paper. Daisy
wheel printer is slower
than dot matrix printer
but better in quality

13. 
A non-impact printer is a type of printer
where the print head does not strike the
paper.
The characters are printed on paper with
different means such as laser. Some
printers use spray ink while other use
heat and pressure to create image .
Non Impact Printer

14. These printer are faster than impact printer. However,
they are more costly than impact printer. They produce
no noise during printing. The printer quality of non
impact printer is better than impact printer
Different non-impact printer are as follows;

15. Laser Printer
A laser printer is a type of non-impact printer that
uses a laser and electrical charge model instead of
the traditional
printing of ink
onto paper. Its
working is similar
to photocopying
machine

16. Laser printer prints
complete page at a time.
It is also known as page
printer. The printing
speed is 12 to 45 page
par minute. It print text
and graphics in high
quality resolution. A
typical laser printer
provides of 1200 DPI or
more. It does not make
much noise

17. Inkjet printer
Inkjet printers are a category of printer in which
printing is done with the help of inkjet technology.
The technology works by spraying ionized ink
directed by magnetic plates onto the paper, which
is fed through the printer. They are commonly used
as home and business printers.
These printer can produce quality text and
graphics in black-&-white and color photos

18. Inkjet printer provides
a resolution of 600 DPL
or more. Its price is less
than laser
printer . Most inkjet
printer can
print from 10 to 35
pages per
minutes

19. A thermal printer is a printer that makes use of heat in
order to produce the image on paper.
Due to quality of print, speed, and technological
advances it has become increasingly popular and is
mostly used in airline, banking, entertainment, retail,
grocery, and healthcare industries

20. PhotoPrinter
Photo printer is a color printer designed to print high
quality photographs. It is also called snapshot printer.
Some photo printer print
photo one or two size
only. For example some
photo printer print
photos of 3*4 inches

21. 
Many photo printer have a built-in card slot. The printer can
print digital photos directly form a media card. Some photo
printer also have built-in LCD color screens. The user can view
pictures before printing them

powered printer. It can be used by mobile users to
print image form notebook computer, tablet
smartphone while traveling

a built-in digital scale. It prints postage stamps. It
allows the users to buy and print digital postage
from their personal computer. The digital postage is
called internet postage
