What is a Printer and How Does It works?

We use printers to create all kinds of hard-copy documents. No matter whether it’s school papers or business reports and everything in-between. Today printers also have a wide range of color choices, making printing HD-quality photos with accuracy and convenience.

It’s fascinating to see how far the printer has come on its journey to this degree of complexity. However, adding an extra level in printing industry services like Same Day Printing Service in London makes a huge impact.


But now it’s time to look at some pre-printing history and how does a printer work. So let’s scroll down to know more about printers.

What is a printer?

A printer is a device that can transfer computerized data and graphics to paper. Printers come in different sizes, costs, speeds, and features.

Depending on your preferences, you can choose a printer that meets all your requirements.

How Does a Printer Work?

The working process of a printer is very simple and easy to understand. As we already mentioned, a printer’s basic purpose is to transfer digital images and text to physical papers.

To do so, printers have built-in software or a driver used to do the converting process. However, a succession of tiny dots reproduced the picture or text on the page.

But the basic procedure may vary due to the various types of printers. That’s why let’s know the types of printers and their working process.

Types of Printers

Inkjet and laser printers are the two most common types of printers on the market today. However, smaller subcategories like Dot Matrix and Solid Ink are also available.


Print heads of an inkjet printer have thousands of tiny holes. At a high rate of speed, these tiny apertures deposited the small ink droplets on paper. This is how a line got printed through an inkjet printer.

Inkjet printers utilize a liquid ink made from either a colored dye or a liquid with solid pigments embedded in it. A perpendicular path is created for paper by the horizontal movement of the print head. An ink droplet is ejected from each print head’s unique holes when the paper passes through.

Thousands of droplets come together to replicate the digital text or picture transferred onto the device. Because the dots are so small, the whole picture seems solid to the bare eyes.


Unlike inkjet printers, laser and LED machines use a similar technique to create images that seem to be solid when seen as a whole. When it comes to generating those small dots, though, the methods used are significantly different. As a result, a laser employs dots manufactured of toner, a tiny powder of solid particles, while an inkjet uses liquid dots.

Lasers are a lot more complicated than inkjet printers. Inkjet printing relies on a much smaller number of steps. A light source (laser/LED), drum (mono) or multi-drum (color), and toner are used in the fundamental process.

To produce an image on paper, a laser or LED is projected onto a charged drum in the shape of the desired picture. As the toner is drawn to the drum’s uncharged portions, it’s delivered to the drum by rollers.

The charged sections resist toner while the uncharged areas attract toner particles which are dragged onto the drum and adhere to the picture. At the same time, the paper is delivered to the drum, where the picture is transferred to the page itself.

Afterward, the paper is run through a heated roller, which melts the toner particles to adhere to the sheet and produce a final picture.

Solid Ink

Solid ink printers are well-known for their ability to produce vivid, colorful prints that stand out. These printers combine the advantages of inkjet and laser printing in one device. An inkjet printer’s print head is used to pump molten wax onto a huge drum unit.

A big metallic roller generates the picture, which is then transferred straight to the paper. A crayon-like material is left behind as the ink dries.

Dot Matrix Printer

The print head of the dot matrix printer includes pins and rests on an ink ribbon to generate letters and pictures. A sheet of paper is resting on top of this ribbon. Pins push into the ribbon as the print head advances over it horizontally, imprinting ink onto the paper. This is how the printer acquired its name, as these pins create a succession of dots.

Features of a Printer

Here’re some factors that you should consider while buying a printer for yourself.


Nowadays, most modern printers offer color printing. But they’re a bit pricey compared to the traditional printers. The ink may be blended or packaged in separate monochrome solid ink printer cartridges depending on the printer.


The sharpness of the text and images on paper is known as resolution. Dots per inch (dpi) measure resolution. 600 dpi is the standard resolution for most low-cost printers.


This factor matters the most if the user needs the printer frequently. Inexpensive printers can only produce between 3 and 6 sheets per minute. A costlier, high-tech printer may, meanwhile, produce pages at a quicker rate.


Most printers include 2-16 megabytes of memory that the user may increase. When printing huge photographs, having more than the minimum quantity of RAM is beneficial and expeditious.


Q) Is it necessary to have a printer connected to my computer?

Answer: To use a computer printer, you don’t need to have an operating system installed. Without a printer, many individuals use their computers every day. The only problem is that if they need to print anything, they will have to go someplace else.

Q) What is the most popular printer?

Answer: Where you utilize a printer has a lot to do with what kind of printer you’ll get. Because of the low initial cost, inkjet printers are the most popular choice for individuals and families. Laser printers are the most widespread in the workplace.

Q) What causes printer malfunctions?

Answer: The printing tray may be corrupt, which might be the root of the problem. It’s also possible that the connection between your computer and printer is to blame.

Q) What to do to clean a printer?

Answer: Cleaning your printer involves using a vacuum cleaner or canister of compressed air to remove dust and debris from the printer’s ink cartridges. The platen or roller should be cleaned if there are streaks or smudges on the paper. You may then clean the printer with a vacuum cleaner or can of compressed air.

Q) How many years can a printer expect to live?

Answer: A printer’s life expectancy is typically between three and five years. Some printers may survive longer if properly cared for and maintained, but eventually, you’ll need to update your device.


Hopefully, you got a clear idea of what a printer is and how it works from the article. From now on, whenever you go to purchase a printer, remember the features.

There are a variety of printers to choose from, and perhaps you’ll find one that matches your needs.
