Plotter in Computer – Definition, Types, Uses & Working Explained
Published: 15 Apr 2026
Many students find it hard to understand computer output devices. They get confused between a printer and a plotter. This confusion makes learning difficult. If you are also facing this problem, you are not alone. In this guide, we will explain what is plotter in computer in very easy words. You will learn its uses, types, and features step by step.
What is plotter in computer? (Definition)
A plotter is an output device in a computer that draws large, accurate images on paper. It works by drawing continuous lines instead of printing dots like a normal printer. It is mainly used for making maps, engineering designs, and building plans that require high precision.
In simple terms, a plotter helps create large, detailed drawings with high accuracy.
Uses of Plotter
A plotter is used to produce large, accurate drawings across various professional fields.
- It is used in engineering to draw technical designs and machine plans.
- It is used in architecture to create building maps and house plans.
- It is used in graphic design for making high-quality artwork and layouts.
- It is used in map-making to draw detailed geographical maps.
- It is used in advertising to design posters, banners, and large prints.
In simple words, a plotter is used wherever large, clear, and precise drawings are needed.
Types of Plotter in Computer
Plotters come in different types, each used for specific drawing and printing tasks.
1. Drum Plotter
A drum plotter uses a rotating drum to move the paper while pens draw the image. The paper moves in one direction, and the pen moves in another direction. It is used for making long, continuous drawings, such as charts and large designs.
2. Flatbed Plotter
A flatbed plotter has a flat surface where the paper is placed. The pen moves across the paper in all directions to draw detailed, accurate images. It is mainly used for high-precision work, such as engineering and architectural design.
3. Inkjet Plotter
An inkjet plotter works by spraying tiny drops of ink on paper. It is similar to a printer but designed for large prints. It produces high-quality colored images and is used for posters and large graphics.
4. Cutting Plotter
A cutting plotter does not draw with ink. Instead, it cuts shapes from materials like vinyl or paper. It is mostly used in advertising, sticker making, and signboard design.
In simple words, each type of plotter is used for different professional drawing and design needs.
How Does a Plotter Work
A plotter works with a computer and specialized drawing tools. It takes instructions from the computer and converts them into drawings on paper.
- First, the user creates a design on the computer using software.
- Then, the design is sent to the plotter as a command.
- The plotter reads these instructions carefully.
- After that, the pen or ink system starts moving on the paper.
- It draws lines step by step to create a complete image.
- Finally, a large and accurate drawing is produced.
In simple terms, a plotter follows computer instructions to draw images with high accuracy on paper.
Features of Plotter
A plotter has many useful features that set it apart from a standard printer.
- It produces large and high-quality drawings.
- It works with high accuracy and precision.
- It draws continuous lines instead of dots.
- It can print on big paper sizes.
- It is used for professional design work, such as maps and building plans.
- It produces clear, detailed output for complex drawings.
In simple terms, a plotter is a highly accurate device used to create large, detailed drawings.
Advantages and Disadvantages of a Plotter in a Computer
A plotter is a useful output device in a computer system. It is primarily used to produce large, high-quality drawings. Like other devices, it has both benefits and limitations.
