There are two main types of printers: impact printers and non-impact printers. Impact printers work by striking an ink ribbon and include dot matrix and line printers, while non-impact printers like inkjet, laser, and thermal printers do not make physical contact and are generally faster and quieter. Line printers can print entire lines at once at speeds up to 3000 lines per minute but have low quality and can only use one font. Dot matrix printers print one line at a time at speeds up to 300 characters per second. Thermal printers use heated pins on special paper but produce low quality prints that fade quickly. Laser printers use laser beams and powdered ink to produce high quality graphics up to 1200 dpi. Inkjet printers use color

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/

Scanner is a device that translates hard copy into soft copy.
It translates data on a sheet of paper to a form that can be stored on a computer.
In other words converting of a document into digital format.
Data can be in either form of text or graphics.
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.

This assignment was made by the help of online web portals. My heartiest thanks to the authors of that portals.
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.
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

2. Printers
Printer is an output device that prints text or
images on paper or other media (like
transparencies). By printing you create
what is known as a ‘hard copy’. There are
different kinds of printers, which vary in
their speed and print quality. The two main
types of printers are impact printers and
non-impact printers.
3. Types of Printers
Impact printers include all printers that print by
striking an ink ribbon. Impact printers use a print
head containing a number of metal pins which
strike an inked ribbon placed between the print
head and the paper. Line printers, dotmatrix
printers are some of the impact printers.
4. Characteristics of Impact Printers
i. In impact printers, there is physical contact with
the paper to produce an image.
ii. Due to being robust and low cost, they are useful
for bulk printing.
iii. Impact printers are ideal for printing multiple
copies (that is, carbon copies) because they can
easily print through many layers of paper.
iv. Due to its striking activity, impact printers are very
noisy.
v. Since they are mechanical in nature, they tend to
be slow.
vi. Impact printers do not support transparencies.
5. Non-impact printers
Non-impact printers are much quieter
than impact printers as their printing
heads do not strike the paper. Non-
impact printers include laser printers,
inkjet printers and thermal printers.
6. Characteristics of Non-Impact Printers
i. Non-impact printers are faster than impact printers
because they have fewer moving parts.
ii. They are quiet than impact printers because there
is no striking mechanism involved.
iii. They posses the ability to change typefaces
automatically.
iv. These printers produce high-quality graphics
v. These printers usually support the transparencies
vi. These printers cannot print multipart forms
because no impact is being made on the paper.
7. Line Printer
Line printers are high-speed printers capable of
printing an entire line at a time. A line printer can
print 150 lines to 3000 lines per minute. The
limitations of line printer are they can print only
one font, they cannot print graphics, the print
quality is low and they are noisy to operate. But
it can print large volume of text data very fast
compared to the other printers. It is also used to
print on multipart stationaries to prepare copies
of a document.
9. Dot Matrix Printer
The most popular serial printer is the dot matrix
printer. It prints one line of 8 or 14 points at a
time, with print head moving across a line. They
are similar to typewriters. They are normally
slow. The printing speed is around 300
characters per second. It uses multipart
stationaries to prepare copies of a document.
11. Thermal Printer
Thermal printers are printers that produce images
by pushing electrically heated pins against
special heat-sensitive paper. They are
inexpensive and used widely in fax machines
and calculators.
Thermal printer paper tends to darken over time
due to exposure to sunlight and heat. So the
printed matters on the paper fade after a week
or two. It also produces a poor quality print.
13. Laser Printers
Laser printers use a laser beam and dry
powdered ink to produce a fine dot matrix
pattern. It can produce very good quality of
graphic images. One of the chief characteristics
of laser printers is their resolution – how many
dots per inch (dpi) they lay down. The available
resolutions range from 300 dpi at the low end to
around 1200 dpi at the high end.
15. Inkjet Printers
Inkjet printers use colour cartridges which combine
magenta, yellow and cyan inks to create colour
tones. A black cartridge is also used for crisp
monochrome output. Inkjet printers work by
spraying ionizing ink at a sheet of paper.
Magnetized plates in the ink’s path direct the ink
onto the paper in the described shape.
