About Computer Printers and Plotters
Computer printers and plotters are used to output industrial data in printed form. There are several different types of products. Direct thermal printers use heat to set sharp, crisp images on non-curling, smudge-proof, heavy-stock thermal paper. Thermal transfer printers use heat and pressure to transfer resin-based ink from tiny ribbons directly onto the paper. Ink jet printers spray droplets of ink through a nozzle onto the page. Laser printers use a laser beam to produce an image on a drum. The light of the laser alters the electrical charge of the drum, which is rolled through a reservoir of toner. Through a combination of heat and pressure, the toner is then transferred to the paper. Liquid crystal display (LCD) and light emitting diode (LED) devices are similar to laser printers, but use LCDs or LEDs to produce an image on the drum. Dot matrix printers strike pins against an ink ribbon to print closely-spaced dots, often with multi-page forms. Line printers use the same technology as dot matrix devices, but are much faster for greater workloads. Other unlisted, specialized, or proprietary computer printers and plotters are also available.
