A Printer is a device that allows you to print text or graphics from your computer onto paper. In other terms, a printer is a piece of hardware that allows you to print hardcopy from your computer onto paper. In this article you will learn How do different types of printers work and printer advantages and disadvantages.

Who Invented Printer?
Johannes Gutenberg, a goldsmith, invented the printing press in 1440, kicking off the Printing Revolution. Samuel Simon of England was granted a patent in 1907 for his invention of using silk cloth as a printing screen.
Remington-Rand created the first high-speed printer in 1953. In November 1971, the Xerox Palo Alto Research Center built the first laser printer, known as EARS. Carlson’s Xerox copier technology was adapted by Xerox Engineer Gary Starkweather, who combined it with a laser beam to create the laser printer
The first xerographic laser printer product, according to the Xerox Corporation, was released in 1977.The inkjet printer was conceived in 1976, but it wasn’t until 1988 that it became well known.
What is a Printer? How do Printers Function?
Printers operate in a very straightforward manner. Printers, help us in transferring digital images and text to paper. They do it with the assistance of a specialised driver that allows printers to transform files into a format that the printer can understand.
Using dots, the image and text are then produced on the paper. The main differentiator between the various printers is the type of printer that you are utilising. E.g., in laser printer the laser beam is used to print.
How Different Types of Printer Work?
1. Inkjet Printers
Each inkjet printer has a print head with thousands of tiny holes. These minuscule apertures spray microscopic droplets of ink onto the printer’s paper at a rapid rate. Inkjet printers employ a liquid ink made from either a coloured dye or a liquid containing suspended solid pigments. The paper travels through perpendicular to the print head as it moves horizontally through the machine.
The individual holes in the print head are activated (typically by heat electrical current depending on the manufacturer) when the page passes past, and a small drop of ink is pushed out onto the page. This method involves thousands of droplets forming together at rapid speed to reproduce the digital text or image being transferred onto the device. Because the dots are so little, the whole image seems solid to the human eye.
2. Laser/LED Printers
Laser and LED printers work similarly to inkjet printers in that the image is made up of many tiny dots that appear to be a solid image when viewed as a whole. The technology used to create those small dots, on the other hand, is significantly different. So, when an inkjet utilises liquid dots, a laser uses toner dots, which are small powders of solid particles.
Lasers are significantly more complicated than inkjet printers. In comparison to inkjet, these machines use a lot more stages in the process. A light source (laser/LED), a drum (mono) or multiple drums (colour), and toner are used in the fundamental process.
To make an image on the page, the drum must first be charged before the laser or LED is projected onto it in the shape of the desired picture. Toner is drawn to portions of the drum where the charge has been knocked off, and a set of rollers transport the powder from the toner cartridge to the drum. The charged portions reject toner, while the uncharged areas attract toner particles, which are drawn onto the drum and adhere to the image’s components.
The paper is also delivered at the same time to reach the drum, which then transfers the image to the page itself. The paper is subsequently fed through a fuser unit (hot roller), which uses heat and pressure to melt the toner particles and adhere them to the sheet, resulting in a final image.
3. Multifunction Printer
A multifunction printer, often known as an MFP printer, is a device that combines a scanner, photocopier, printer, and fax machine into one device. Some models additionally have photo printing capabilities, allowing users to print high-quality images on specialist photo paper. They are available in a range of sizes, ranging from small desktop units to huge standing office workstations.
One of the main benefits of a multifunction printer is that it is a cost-effective solution for most businesses of any size that can often help you save on energy costs from powering multiple different machines. There are also both leasing and purchasing options for your machine, so you will be able to find something that fits your budget.
4. Dot Matrix Printers
Inkjet printers are similar to dot matrix printers. They function by employing a movable head that prints in a line-by-line fashion.
Dot matrix printers, on the other hand, use an impact ‘head and ribbon’ mode of printing, as opposed to inkjets. This approach is quite similar to that of a typical typewriter, in that it leaves a mark by punching tiny holes through the ribbon and into the page.
Despite their reputation as antiquated, dot matrix machines are ideal for invoicing and warehouse packing/picking slips where many copies are required. Dot matrix printers can print many sheets at once, printing the white front sheet first, then the coloured carbon copies behind it. Dot matrix printers are more dependable than laser or inkjet printers in general, especially in unclean locations like warehouses or car garages.
5. Solid Ink Printers
A laser printer that prints with solid wax inks that must be melted into a liquid before use. Solid ink printers spray ink onto a drum rather than directly onto the paper, like inkjet printers do. Because the drum can be more precisely controlled than moving paper, sending the ink to the drum first and then to the printer results in better colour registration.
Before entering the printhead’s plumbing, the solid wax ink is melted and transformed into a liquid. The piezoelectric drop on demand method is commonly used to jet ink from the nozzles. In this case, the printhead is the same width as the paper.
With its crayonlike cartridges, Tektronix, Inc., whose colour printer division was acquired by Xerox in 2000, pioneered the solid ink printer market. The colour fidelity of the Tektronix printers was stunning when they were first released in the mid-1990s, and their print rates were faster than an equivalent-priced laser printer since colours were printed in one pass rather than four.
Laser printers, on the other hand, require the application of each of the four CMYK colours to a secondary accumulator drum one at a time before the image is transmitted to paper. In one pass, Tektronix’s technique applies a four-color solid print mirror image to the drum.
6. 3D Printers
Additive manufacturing, also known as 3D Printing, is the technique of creating Three-Dimensional solid items from a computer file.
Additive manufacturing technologies are used to create 3D printed objects. An object is built in an additive technique by laying down successive layers of material until the object is complete. Each of these layers can be viewed as a cross-section of the item that has been lightly cut.
Subtractive manufacturing, which involves cutting or hollowing out a piece of metal or plastic with a milling machine, is the total opposite of 3D printing. When compared to traditional production methods, 3D printing allows you to create complicated shapes with less material.
What Are The Different Types of Printer Advantages And Disadvantages?
- we can see computer printer is now common in house and office uses.
- Due to printer, we can fulfil our daily needs.
- We can print any documents, books, etc. with the help of printers in very short time.
- If we buy printer then we don’t have to go out for print and that saves our time and money also.
- According to new technology new printers comes like laser printers which solves our most of difficulties like laser printers can prints fast and not doing any kind of noise.it can also prints on different materials also. And it can print alphabet and graphs also.
- In many offices all are buying personal Printers for printing which can saves money and time also.
- We can print graph, chart, photo, etc. with the help of printers and also, we can print large copies and colour print.
- 3D printing is our future. they can make any big objects from documents. We can do any kind of changes in dimensions, length, breadth from software and make 3D Print.
- If we have printer then we have to be prepared for their expenses like pages, ink, toner, etc.
- If we print colour photos then it cost more than the normal photos.
- The more pages you print it expenses also increase like electricity bill, ink, pages, etc. And we have to use printer on daily basics otherwise it affects our ink and toner in monsoon season.
- Laser Printers is too much costlier than other printers and its expenses is also more than other printers it prints are also expensive because of their maintenance cost.
- 3D printer is also costlier than laser printer. We cannot print many objects at one time on 3D printers.it takes time to print any objects in 3D printer. Then also in India many companies are using 3D printers for their works.
Which was the Best Printer for Home Use?
The two types of Printers that most home users use are laser and inkjet Printers. An inkjet printer can be a fantastic alternative if you’re looking for a low-cost printer to print papers and images. If you want the ease of making copies, scanning pages, and possibly sending faxes all in one machine, you might want to investigate an all-in-one model.
You might select a Laser Printer if you usually print black-and-white documents and have a high print volume because of its speed and cheaper cost per page produced. A colour laser printer, on the other hand, is unlikely to be cost effective for most home users.
