Introduction
Back then whenever I need to print my study materials, I will simply just connect my laptop to the printer set aside with a connecting cable. And then all I need is to click the print option, the materials will be printed, simple as that. I always thought that was how easy a printer works. After the second lecture of Information Technology 061, which is about computer hardware, I had learnt that there are various types of printers and each with different characteristics. I had never wondered how does a printer function exactly and what makes each type of printers different from one another.
Printers
A printer is an output device that produces texts and graphics on a physical medium such as transparency film, posters and various types of paper. Printers are one of the most used peripherals on computers and are usually used to print photos, images, text and store as hard copy. The printed materials and information are the hard copy which is in a permanent and readable form. There are a wide variety of printing devices available due to different needs of people all around the world. Thus, printers are existed with different speeds, functions, prices and printing methods.
Various Ways of Producing Printed Output
A few years ago, the earliest method people used for printing documents would be the same as me, which is connecting a computer to a printer with a printer cable. The advancement of modern technologies is increasing rapidly throughout the years, providing a variety of printing options such as wireless printing technology and direct printing from a camera. Nowadays, without uploading or downloading the images from a digital camera into files, people also could easily print the images they needed. There are t...

Conclusion and Personal View
Through my lecturer detailed explanation about the printers, I had learnt the various types of printers and their characteristics. I had understanding in further about how does a printer functions to create images or characters onto the paper. For example, impact printers functioning by involving the process of striking while nonimpact printers functioning by spraying, laser beam and etcetera. Besides, with my understanding about the printers, I could specify my needs and purchase the printer which is suitable for me. Such as how much is my budget; Do I need a color printer or black and white printer; Do I print directly from memory card or media card; Do I need wireless printing capability.
(Hook) Throughout the history of man, there has been numerous achievements in human communication that have changed lives greatly. (Bridge) One of the milestones in communication was the printing press. (Background Info) In 1450, Johannes Gutenberg invented the printing press in Germany. By 1600, more than 200 million books had come off the presses. Therefore, an average person living in Europe at the time could own a book, such as a copy of the Bible. As the number of books being produced increased, the literacy rate increased as well. As a result, people started to read and explore topics such as science, religion, and geography. The printing press led to a major price drop in books, more knowledge learned, and many significant events in history, such as the Age of Exploration and the Reformation. (Thesis) I believe that the most crucial consequence of the printing press was the Age of Exploration.
Throughout history, there have been many inventions to help humans communicate, such as the telephone, typewriter, and many more. One great milestone was the printing press. The printing press was invented in 1,450 CE by Johannes Gutenberg. The printing press is a machine that could quickly mass produce books at a cheap cost. He created the invention in Germany. The printing press lead to a higher distribution in books at a lower price. As a result, the literacy rate was increased and more people were able to learn about science, religion, and geology.
Wood-type printing allowed new typefaces to be created and used for printing cheaper than ever before. Technological advances permitted machine-set typography to be printed on machine-manufactured paper with high-speed steam-powered printing presses. The use of color lithography passed the aesthetic experience of colorful images from the privileged few to the whole of society.
To put it more vividly, the printing process of a 3D printer is like making a melaleuca cake with various materials. And “the materials”, as the inventor of this technology Charles W. Hull once wrote, “include polymers, metals, ceramics, composites, food, probably other things, too”. So, imagine these materials can be melted like cream and stretched as thin as the hairline. The printer uses these lines to draw the outline of the object based on the inputted or scanned blueprint firstly and then overlaps the lines upon the previous frame just like decorating the cake with cream.
The printing press is a moveable type machine that is used for transferring text and images to paper using ink. The machine helped change society from making hand written books to producing books more rapidly. The printing press was more effective when it came to text and images being seen on paper. When material had to be hand written it was hard to read, but the printing press made reading a lot easier. The printing press invention became more efficient when wanting to spread work faster.
Every single program will be able to create a virtual diagram and outline of the concept being implemented on the printer. Then the program divides the concept into digital ...
Nowadays, the popularity of these media is more to electronic media than printed media because their trying to dominate each other. A printed media have its own importance and popularity which cannot be replaced by anyone else. When though there is a tight competition between the newspapers and electronics medium among variety of newspapers increasing day to day which has made the print media cheaper, qualitative, informative and fast. The printed media is more accurate information details. The electronic media just hire people based on looks rather than journalism skills because the journalists and editor of newspapers are more efficient and experienced. The utility of print media will always remain informative to help the user. Printed media on deeper research of particular topic
According to Pew Research Center's Journalism Project, the overall drop in newspaper circulation began in 1989 and has been at a gradual decline of 1% a year since (Pew Research Center's Journalism Project, 2007). 1989 is also the year of the birth of the World Wide Web(Home.web.cern.ch, 2014).
The printing press was the invention of moveable metal type paper and was able to print books, newspapers, bibles and much more. It was the start of something new and evolving throughout the entire world. Gutenberg’s creation is known to be the most significant invention in history. It is the most prompted creation that people could ever ask for, and for many extraordinary reasons. The reason why the printing press was so useful than just any other invention is because it spread everywhere.
The “invention and manufacture of standard movable type allowed the beginning of the printing industry” (Thompson 210). “The first printed encyclopedia, the Catholica, appeared in 1460 and the following year a Strasbourg printer, Johan Mentelin, produced a Bible for laymen” (Johnson 18). The invention of printing made a large amount of material cheaply available (Thompson 210).
