This document discusses different types of printers. It begins by defining a printer as a hardware device that takes computer data and generates a hard copy. It notes there are two main types: impact printers, which use pins to strike paper, and non-impact printers, which print without striking paper. The document then provides details on specific printer types, including daisy wheel, dot matrix, inkjet, and laser printers. It concludes by defining all-in-one printers, which combine printing, scanning, copying, and faxing functions.
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.
There are two types of printers.
Impact printers
Non-Impact printers
In computers, a printer is a device that accepts text and graphic output from a computer and transfers the information to paper, usually to standard size sheets of paper. Printers are sometimes sold with computers, but more frequently are purchased separately. Printers vary in size, speed, sophistication, and cost. In general, more expensive printers are used for higher-resolution color printing. https://isotechline.com/

In computing, a printer is a peripheral device which makes a persistent human-readable representation of graphics or text on paper or similar physical media.[1] The first computer printer design was a mechanically driven apparatus by Charles Babbage for his difference engine in the 19th century; his mechanical printer design was not built until 2000.[2] The first electronic printer was the EP-101, invented by Japanese company Epson and released in 1968.[3][4] The first commercial printers generally used mechanisms from electric typewriters and Teletype machines. The demand for higher speed led to the development of new systems specifically for computer use. In the 1980s were daisy wheel systems similar to typewriters, line printers that produced similar output but at much higher speed, and dot matrix systems that could mix text and graphics but produced relatively low-quality output. The plotter was used for those requiring high quality line art like blueprints.
Devices that output hard copy
An external hardware device responsible for taking computer data and generating a hard copy of that data. Printers are one of the most commonly used peripherals and they print text and still images on the paper.
Impact printers use a device to strike an inked ribbon, pressing ink from the ribbon onto the paper.
Non-impact printers use different methods to place ink (or another substance) on the page.
(1) DPI:
It is a measurement of printer’s resolution indicating how many ink dots can be placed by the printer in one square inch. The higher the DPI, the sharper is image. Image quality – Measured in dots per inch (dpi). Most printers produce 300 – 1200 dpi.
(2) Type of printer:
Each type of printer has its own capabilities of printing. Some types of printers produce high quality print while other produce low quality print.
(3) Print Mode:
The printing mode may also affect the quality. For example the draft mode increases the print rate but quality is reduced.
(4) Toner:
The quality and amount of toner also affects print quality.
Printer is an output device. There are several types of printer. Operation and advantage and disadvantages are presented on this assignment. This assignment was made as an assignment for university's course.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

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.

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.

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:

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

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.
