HARD-COPY DEVICES

---

We can obtain hard-copy output for our images in several formats. Eg: Dot matrix printer, laser printer & inkjet printer are commonly used.

Drafting layouts and other drawings are typically generated with ink-jet or pen plotters. A pen plotter has one or more pens mounted on a carriage, or crossbar, that spans a sheet of paper. Pens with varying colors and widths are used to produce a variety of shadings and line styles. Wet-ink, ball-point, and felt-tip pens are all possible choices for use with a pen plotter. Plotter paper can lie flat or be rolled onto a drum or belt. Crossbars can be either moveable or stationary, while the pen moves back and forth along the bar. Either clamps, a vacuum, or an electrostatic charge hold the paper in position. An example of a table-top flatbed pen plotter is given in Figure below, and a larger, rollfeed pen plotter is shown in Fig.below
