2. What Is a printer?
 It is an external hardware device
responsible for taking computer
data and generating a hard copy of
that data.
 Printers are one of the most used
peripherals on computers and are
commonly used to print text,
images, and photos.
 World's first computer printer was a
19th-century mechanically driven
apparatus invented by Charles
Babbage for his difference engine.

3. What are its major types?
 Major types of printer Printers can
be divided into two main
groups, impact printer and non-
impact printer.
 Impact printer-Impact printer
produces text and images when
tiny wire pins on print head strike
the ink ribbon by physically
contacting the paper.
 Non-Impact printer-Non-impact
printer produces text and graphics
on paper without actually striking
the paper.

5. “Daisy Wheel Printer”
 A daisy wheel printer is
basically an impact
printer consisting of a
wheel and attached
extensions on which
molded metal
characters are mounted.
A daisy wheel printer
produces letter quality
print and it can’t
produce graphics
output.

6. Daisy Wheel printer:
Merit Demerit
•Can Print on multi-part
forms or carbon copies
•Low printing cost per
page
•Can be used on
continuous form paper
•Reliable, durable
•Noisy
•Limited Print Quality
•Low Printing Speed
•Limited Color Printing

8. DOT MATRIX PRINTER:
 It is an impact printer that
produces text and graphics
when tiny wire pins on the print
head strike the ink ribbon.
 They were highly popular
during the 1980s and were the
world’s most common and
relied upon printing instrument
for a long time.
 Now they have become
obsolete.

10. Dot matrix printer:
Merit Demerit
•Can Print on multi-part
forms or carbon copies
•Low printing cost per
page
•Can be used on
continuous form paper
•Reliable, durable
•Noisy
•Limited Print Quality
•Low Printing Speed
•Limited Color Printing

12. Ink Jet printer:
 They are non-impact
printers which print text and
images by spraying tiny
droplets of liquid ink onto
paper.
 They use CYMK color
combination for generating
all other colors.
 The ink is stored in
separate, replaceable
cartridges.
 They are the most popular
printers for personal use.

13. INK JET printer:
Merit Demerit
•Low cost
•High quality printing with
good color density and
smooth details
•Capable of printing in
vivid and wide-range of
colors
• Easy to use and maintain
•Print head is less durable
•Ink Cartridge replacement
is an expensive affair
•Not good for handling
volume printing duties
•Printing is not as fast as
other printers, say laser
printers.

15. Laser Printers:
 Laser Printers are non-impact
printers which can print high
resolution images with high
speed.
 Their printing resolution varies
between 600dpi-1200dpi.
 They use toners(black or
colored powders), instead of ink,
for printing purposes.
 Can print between 4-20 pages
of text per minute.

16. LASER printer:
Merit Demerit
•High Resolution printing
•High printing speed
•No smearing
•Low cost per page (as
compared to ink jet
printers)
•More expensive than Ink-
Jet printers to maintain
and use
•Are less capable of
printing images with high
vividness
•Toner replacement and
drum replacement is
expensive
•Bulkier than ink-jet
printers

18. ALL-IN-ONE Printer
 All-in-One multifunction
printer(MFP) is also known
as all-in-one printer or
multifunction device(MFD).
 It includes printer, scanner,
copier and fax.
 It is gaining high-popularity in
small offices and business
store application etc.

19. All-in-one printer:
Merit Demerit
•Low cost-high value for
money
•Takes up less space,
input and resources
•Easy to use
•Good for non-specialized
but diverse role
•If one component
develops faults, the entire
machine may get affected
•‘Jack of all, King of non’-
issue
•Fails to provide quality
and efficiency of dedicated
devices

20.  In fact computer world is incomplete without printers
in the modern age of technology. A printer is one of
the basic needs of every computer user and one
can not utilize computer resources properly in the
absence of a quality printer.
