What is a printer?
This device holds the responsibility of taking the information and presenting it on a paper sheet. This paper sheet has a standard size. It gets the information as an output from the computer. This information can be a text or an image.
When and where was the printing press invented?
It is a very useful invention, Had it not been invented we would not have seen magazine, books etc.
It was invented in 1440 in the Roman Empire. Before its invention, people had to write everything by hands. Wax also used.
Johan Gutenberg is the man behind this wonderful invention. He used metals for introducing the machine to people. In the beginning, it was considered as a luxury. This invention became much popular among the people especially the lower class ones.
Who invented the printer?
Chester Carlson invented electrographic mechanism in 1938. It refers to a printing process. This later became the basis for the invention of laser printers.
For almost 3 years nobody was interested in this invention than in 1959 people saw the Xerox copier. In 1953 Remington Rand introduced the high-speed printer.
Different types of printers:
There are following types of printers:
- Non impact
Impact vs. non-impact printers:
The first one print using an inked ribbon which it strikes on the paper by pins.dot matrix, daisy wheel, drum and line printers are of this sort.
Non-impact printers are quieter as they do not use any striking mechanism for printing. Inkjet and laser printer are of this sort.
All in one colour laser printer:
The term all in one is used for a device that is multi functional. Thus such printers perform the functions of multiple printers, the printing you think to do with more than one printer, and this one can handle those tasks alone.
For business, this one is quite valuable. It offers a good speed. Laser printers do colour printing making in using the four cartilages CMYK. CMYK refers to Cyan, Magenta, Yellow and Black.
Some of the features of multifunctional printers are:
- Availability of network printing
- Availability of different connection types like USB, parallel etc
- Print drivers that support the Operating system
- Duplex printing
- The format of papers.
Its duplex printing feature is explained below:
All in one colour laser duplex printer:
Multifunctional printers have this ability of duplex printing. They have a duplexer. In this printing, both sides of paper get printed. This work is done automatically.
If this ability is not present in a printer then you can only perform the simplest printing which printed on the single side of the paper only. If you want to print on both sides in this case then you will need to do it manually. It will not be done automatically.
How does laser printer work?
They were introduced in 1970.The technology used in printing by this one is referred to as drum and laser. The image or text to be printed is projected by the laser on the drum.
The drum is cylindrical in shape and keeps rotating. The drum uses the powdered ink and prints the image or text on the paper.
all in one colour laser printer wireless:
No Ethernet cable is used in this case. All work is done wirelessly. It can perform printing from multiple computers if connected to a network. Thus it makes use of a wireless link for communication instead of any Ethernet cable or any other of the sort.
Black and white laser printer:
- They cannot do colour printing. For this reason, they are quite cheaper than the coloured ones.
- They are also referred to as monochrome printers.
- They are much faster also.
- They are best for text printing in the case when no colour is required.
- The quality of printing is very good.
- They are much lighter and smaller
They belong to the non-impact printers. It prints by spraying ink. This is done through an electrical field. This electrical field is responsible for arranging those ink particles into characters. Then this ink gets absorbed and dries. You can use different ink colour.
The example of impact printers:
Some of them are explained below:
1)Dot matrix printer:
It’s printing head consists of about 9-24 pins. Characters on paper are forms by these pins. Basically, these pins create dot patterns on the papers. The one with 24 pins is considered to be a good quality as it produces more dots that form characters.
If there will be more pins than the character in the paper would be much clearer and visible, It works by the striking of pins on the ribbon that has colour strips.
If you want to do colour printing with it. You will have to change the black ribbon with the colour ones. They can easily print about 100-600 characters per seconds.
2)Daisy wheel printer:
It was introduced in 1969. The man behind this awesome invention was David S.Lee. It consists of a disk that is metallic or made up of plastic. This disk is referred to as daisy wheel.
It also consists of a hammer that strikes the character in an ink ribbon to get the characters printed on the paper. They cannot do bitmap graphics printing.
It was much popular till the 1980s but not much longer after that period. The reason behind this was that it was much noisy and slow. Also, the printing quality was not very good. This technology can now be seen in some typewriters.
This one prints one line at a time. IT has the capability of printing around 3000 lines per minute. Thus it is very fast. It has following 2 types:
- Drum printers
- chain printers.
It consists of a drum; the characters get printed on the paper by the hammer. The drum keeps on rotating. Thus they are much noisy as they use hammering in the printing process.
b) Chain Printers:
It consists of chain on which characters are placed. The chain rotates and the printing of characters is done by activating the hammer.
The printing mechanism in this one uses a metal band. The band spins around the hammer. They have the capability of printing around 2000 line per minutes.
what is a 3d printer?
It allows you to print a 3d object. Layers of material are used to print the desired 3d object. The layers are sliced horizontally. You can use object of your desired shape and size.
It makes use of various technologies. FFF (Fused Filament Fabrication) is one of those technologies. In this technology, heating is used to melt a thermoplastic material and then the material is deposited.
Stl files are of the sort. They are the one that is most commonly used for this purpose. You can use it to get your models transformed into 3d objects.
when was the 3d printer invented and who invented it?
It was invented in 1984. Name of the inventor is Charles W.Hull. He started working on this awesome technology in 1980. Stereolithography technique was used in this process. He used photopolymers which can also be called ultra violet lights.
Types of 3d printer:
It uses different technologies which may be referred to as its types. These are:
- DLP stands for Digital Light Processing.
- This technology was introduced in 1987.
- Its popularity increased a lot in the production of projectors.
- It consists of a semiconductor chip which has digital mirrors on it.
- The light source is arc lamp in this case.
- A transparent container has a plastic resin in it in liquid form
- It uses less material than the Stereolithography technology
- SLS stands for Selective Laser Sintering
- This technology uses a laser to get 3d object oriented.
- It was developed in 1980
- Professor Joe Beaman developed this awesome technology
- FDM stands for Fused Deposition Modeling
- It was introduced in 1980.
- It was developed by Scott Crump.
- FFF(Fused Filament Fabrication) technology is quite identical to this technology.
- The products it printed can be used in high performance.
- It is the only technology that provides products for good mechanical and chemical qualities.
- It can easily print object that has complex geometrical structure.
- EBM stands for Electronic Beam Melting
- It uses the electronic beam for printing.
- It requires very high temperature up to 1000 degree centigrade
- It is a bit slow and expensive. This is the main reason this technology did not get much popularity.
What is a scanner?
It is a hardware device that takes an image from a physical source and converts it into digital form. This digital form of the image can then be stored on your PC.
Thus it one of the reliable ways people use t transmit images. You can modify or edit the image that gets saved in your PC after scanning it via a scanner.
They are attached to your PC by a SCSI. SCSI stands for Small Computer System Interface.
types of scanners:
It’s some most popular types are explained below:
- Integrated scanner
- Flatbed scanner
- Drum scanner
- Portable scanner
- Sheet Fed Scanner
- Hand Scanners
- Production Scanners
- Photo scanners
- This is the most modern types of scanners.
- This one is used in ATM machines.
2) Flatbed Scanners:
- They have a flat glass pane on which the photograph or the document to be scanned is placed.
- Flat objects can be best scanned by this scanner.
- A light is present beneath the glass in order to illuminate the photograph or the document.
- A digital sensor is also present.
- Their settings can be controlled via software. You can change the setting of what sort of scan you desire. You can get a low or high scan as per your choice by changing the settings firm the software.
- Some of these scanners have the capability of scanning both sides of the photograph or the document placed for scanning at a time.
3) Drum Scanner:
Their main role comes when the captured image is to be reduced in a very high resolution. It can also be referred to as the upgraded form of the normal flat bed scanners.
4) Portable Scanners:
Their main role comes into play when you are not in your home or office and a need arises to scan something. You scan the images. The image gets stored in it and when you get back to your home or office you can move that scanned image into your PC.
5) Sheet Fed Scanner:
- In this scanner, the images move along the beam and the beam itself does not moves.
- Single sheets are mostly scanned by this scanner, Books aren’t scanned using this one.
6) Hand scanners:
They are also referred to as handheld scanner. They are smaller in size so you can easily drag them and scan whatever you desire. You can plug them into the port of your PC. Their light source ar e little bit weaker which make their accuracy level low.
- When a need arises to scan multiple documents in a short span of time then you can use such scanner, They can do this task quickly.
- Businesses and large companies are the target market for this scanner.
8) Photo scanners:
- They have the capability of creating the digital form of the photographs that are printed.
- They have a slot on which the photograph is placed.
- Thus they are much fast and can produce a very high-quality image that can be used for editing digitally.
What are OCR document scanner and OCR technology?
This technology allows you to convert the document into a form that is editable. The document can be scanned documents, images or any other of the sort.
This technology is quite useful. Ok, let’s have a thought that your friend sent you a document by an email. Now the question that arises is how will you scan it? This is the point where OCR software comes into play. It will convert this document into an editable form so that you may edit it easily.
How does OCR text recognition work?
It consists of many steps and several algorithms to achieve the editable form any scanned document.
- First, the image is loaded then its quality and orientation are improved. Lines are removed and the page is analysed.
- The work that comes next is of detecting the lines of text.
- The next step is of analysing the broken characters.
- Then the characters are recognized and the file is saved.
Thus you would have now a good knowledge of all in one colour laser printer And scanners. You would have briefly seen what the different types of printers and scanners are. Sound knowledge of these hardware devices will benefit you a lot.
They have a lot of importance in our daily life. wireless multifunctional laser printers allow you to do multiple works from a single device making your work easier.
