What is Printer | Parts – Working | Types & History
Published: 15 Apr 2026
Have you ever wondered how a document on a computer suddenly appears on paper? Many students use printed assignments and pictures every day, but do not know how this process actually works.
In this article, you will learn what a printer is, its parts, how it works, different types of printers, and why printers are important.
Definition
A printer is an output device that prints text, images, and documents from a computer onto paper. It converts digital information into a physical copy called a hard copy.
Working
A printer works by receiving a print command from a computer or mobile device. The printer processes the information and places ink or toner onto paper to create text or images. Finally, the printed paper comes out as a hard copy of the digital document.
Parts of a Printer
A printer is made up of several important parts that work together to print documents and images on paper. Each part has a specific function that helps the printer operate smoothly.
1. Paper Tray – Holds the paper that will be used for printing.
2. Ink Cartridge / Toner Cartridge – Contains ink or toner powder used to create text and images.
3. Print Head – Sprays or places ink onto the paper during printing.
4. Rollers – Move the paper inside the printer while printing.
5. Control Panel / Buttons – Used to turn the printer on, start printing, or cancel tasks.
6. USB Port / Wireless Connection – Connects the printer to a computer, laptop, or mobile device.
History
The history of printers began with the Epson EP-101, introduced in 1968 by Epson, which became the world’s first compact digital printer and marked the start of modern computer printing.
Later, in 1984, the IP-130K (also known as the SQ-2000) was developed, improving printing speed and quality for computer systems. These inventions helped printers evolve from large machines into the fast and user-friendly devices we use today.
Types of Printers
- Inkjet Printers – These printers spray tiny drops of liquid ink onto paper and are commonly used for home and photo printing.
- Laser Printers – These use toner powder and a laser beam to print fast and high-quality documents, mostly used in offices.
- 3D Printers – These printers create real 3D objects by building them layer by layer using special materials.
- LED Printers – Similar to laser printers, but they use LED light instead of a laser to produce images on paper.
- Solid Ink Printers – These use solid ink sticks that are melted before printing, producing bright and vibrant colors.
- Dot Matrix Printers – These print using a moving print head that strikes an ink ribbon to form characters; mostly used for receipts and bills.
- Multifunction or All-in-One Printers – These combine printing, scanning, copying, and sometimes faxing in one device.
- Thermal Printers – These use heat to print on special thermal paper, commonly used in shops, ATMs, and billing systems.
- Plotters – These are large printers used to print big drawings like maps, architectural designs, and engineering plans.
