Thanks for taking the time to discuss this, I feel strongly about it and love learning more on this topic.

Take a look at the guide below to learn about the advantages and disadvantages of the different types of printers on the market, from laser printers to inkjet and everything in between.

When buying a printer for your business, the choice is primarily between one of two types: inkjet or laser. An ink jet printer works by spraying tiny jets of quick-drying ink onto a page. A laser printer distributes a powdery substance called toner over a statically charged drum that rolls over the paper, distributing the print onto the page; heated rollers then cook the toner permanently into place.

The information below discusses some examples of output devices including their uses, advantages and disadvantages. The ICT Lounge. Section 2. Once data has been input into a computer system and processed, it is now 'useful information'.

This information is ready to be output sent out. In this section you will learn about the different types of output devices that are commonly in use. Key objectives of this section:. Know the purpose of and be able to identify different output devices. Be able to discuss advantages and disadvantages of each output device.

Output Devices what are they? Overview of Output Devices:. A computer monitor screen is an example of a commonly used output device. Printers are another example of a commonly used output device. Output devices are part of the 4 main hardware components of a computer system: Input Devices - these get data into the computer Processor - this does something with the data to make it useful information Output Devices - these show the results of processing Storage Devices - holds the data in the system.

The image below shows where output devices fit into a computer system:. This diagram shows where output devices fit into a computer system. Some devices produce a temporary output. For example:. Some devices produce a permanent output. Examples of Output Devices. The table below shows you some examples of output devices.

Click each device to move to more information:. CRT Monitor. Output devices send processed information OUT of a computer. The following sections will help summarise each of the manual input devices. For each one you will see:. CRT Monitor cathode ray tube. CRT monitors are very bulky and take up a lot of desk space. Light pens can be used with CRT's to produce drawings and designs directly onto the screen.

Screen glare can be a problem with CRT's. CRT stands for 'cathode ray tube'. These are the old , bulky , heavy monitors that are still in use today although being used less and less. These are the least expensive types of monitor. TFT's are replacing CRT's largely because they produce a higher quality screen image and take up far less space.

CRT's produce an image Made up of tiny dots by firing Electron Beams against a Phosphor Screen Each dot is coloured Red , Green or Blue of different intensities which produces a vast amount of different colours. These dots combine to create millions of different colour shades. CRT Monitors allow users to instantly see outputs from the computer.

Users would be able to see words they are typing into word processors. Users could also see changes that they are making to an image in graphics editors like Photoshop. CRT's are also used with light pens to allow drawings to be created on screen. Can be used with light pens to create drawings on screen. They are very large and bulky which means they take up large amounts of desk space. Note: their large size and weight also make them difficult and dangerous to move.

Produce a larger range of colours than TFT monitors. They create a lot of heat and have been known to cause fires. The screen angle is better than with TFT's. Screen glare when in direct light makes viewing difficult. Note: they are also prone to 'screen flicker' which can cause headaches and eye strain.

They also need more power than TFT's to operate more expensive to run. TFT Monitors thin film transistor. TFT screens are light and are perfect as displays for portable devices such as laptops. TFT's are also used as displays in mobile phones. Their lightweight makes TFT's easy to mount on walls.

TFT stands for 'thin film resistor'. These are thin flat screened monitors that are commonly seen today. As they become cheaper, these have taken over from CRT monitors as the most popular computer screens.

TFT's are used with the newer desktop PC's , laptops and mobile phones. TFT screens are made up of thousands of tiny pixels. Each pixel has 3 transistors - red , green and blue and each transistor can produce different intensities.

This allows huge amounts of colours to be produced A back light is used to shine light onto these pixels in order for the colours to be produced. In order to light a single pixel, tiny windows can be opened and closed to allow the light to pass through and onto the pixel. TFT Monitors allow users to instantly see outputs from the computer.

They are used as screens in laptops and also mobile phones. Their thin and light design helps the laptop remain portable light and easy to transport. Lightweight so they are perfect for portable laptops and wall mounting.

Images can appear unclear when viewed from an angle. They are very thin and do not take up as much desk space as a CRT monitor. Lower picture quality definition compared to a CRT monitor. They use less power than CRT monitors cheaper to run. Cannot be used with Light Pens yet.

They emit less radiation than CRT monitors. They produce less heat than CRT's. Laser printers are popular for environments that require fast high-quality printouts. Laser printers can handle very large print jobs. Colour laser printers are expensive to buy and run.

Toner cartridge these contain toner power. These produce high quality hard copy outputs on paper. Laser printers use Toner pressed on a page to produce printed documents. They can print large amounts of pages at a very quick rate. You can buy both black and white and colour laser printers. They use a buffer memory which stores the information for the whole document before the pages can be printed out. Once you press print, the document is sent to the printers memory RAM and stored there.

The printer will then output whatever is in the memory when it is ready to do so. Think of the Buffer Memory as a kind of waiting room. Laser printers work by using a laser beam to 'draw' onto a drum.

The laser leaves a positive electric charge on the drum in the places where it drew. A special power known as 'toner' is sprayed onto the drum and it sticks to the parts that contain the positive electric charge.

The drum is then pressed onto a sheet of paper and the paper is heated fused so that the toner is bound to the paper. Very useful for printing where noise levels need to be kept low Like in an office where people need to concentrate or use telephones etc. Good at producing high quality printouts very fast. Good for environments where high volume of printing is required lots of printouts. This is because they have a low printing cost per page.

This is because they need to be able to keep up with the printing demands of many computers. Popular with: Schools Businesses Offices. Very fast at printing documents. Environmentally unfriendly produce ozone. They also use more power than inkjets. Toner cartridges last a long time and don't need to be replaced often.

Types of Printers and Their Advantages – Updated for 2020

When the time comes to purchase a printer for your business, understanding the advantages and disadvantages of the different types of printers available may seem daunting. However, you should take the time to compare more than just the original purchase price of a device when making your decision. Comparing the ongoing maintenance costs, overall size, speed and functionality of a printer will help to ensure you choose the model that best meets the need of your business. Laser printers get their name because they use laser technology to transfer the images you print to paper. The fastest printer option, a laser printer typically has a higher purchase price but the overall cost of ownership tends to be less than that of an inkjet printer. For example, although the upfront cost of laser toner cartridge may seem high, the cartridge often lasts for thousands of pages, possibly reducing the number of replacements needed each year.

Advantages and Disadvantages in Types of Printers. Remember also that there is variation among printers of both kinds and while the rule that laser laser printers and the need for four different cartridges makes the savings less significant.


Types of Printers | List, Category, Impact, and Non-impact Printer

The information below discusses some examples of output devices including their uses, advantages and disadvantages. The ICT Lounge. Section 2. Once data has been input into a computer system and processed, it is now 'useful information'.

Each printer has different pros and cons which make it more suitable for one task, and perhaps less suitable for another task. Generally, printers can be divided up into different categories depending on their mechanisms. Inkjet printers are likely to be a better choice for people using printers at home , whilst laser printers are better for business and office use. The names of each type of printing are pretty self explanatory. Inkjet printing is just spraying or jetting tiny drops of ink onto a sheet of paper to give an image.

Introduction to Computing. There are two types of printers. An impact printer makes contact with the paper. It usually forms the print image by pressing an inked ribbon against the paper using a hammer or pins.
