Plotters are used to produced high quality drawing such as maps, circuit diagram and posters".
Plotters are hardcopy output devices. They are mainly used by architects, engineers, and others who need to generate high-precision graphical output of large sizes on papers Ploners are more expensive than printers.
Types of plotters
- Flatbed plotters
A flatbed plotter plots a design on a sheet in such a way that the sheet is spread and fixed over a rectangalar flatbed table. In such plotters the pen holding mechanism is designed to provide all types of motions under the computer control, necessary to draw a design or graph. Most flatbed plotters have one or more pens of different colors and width.
2.Drum platters
In the drum plotter the paper, on which the design has be made is placed over the drum, which can rotate in both clockwise and anti-clockwise direction. The drawing pens at moted on the drum During rotation of the drum the pens move left and right and create the desired image on the paper. The advantage of drum plotter is that the length of the plot is almost unlimited and the width of the image depends on the width of the drum.
