Dot-Matrix Printer an impact printer that produces printed images when tiny wire pins on a print head mechanism strike an inked ribbon. Line Printer is a high speed impact printer that prints an entire line at a time. Two popular types of line printers used for high volume output are Band and Shuttle-matrix. Nonimpact Printer forms characters and graphics on a piece of paper without actually striking the paper. some spray ink, while others use heat and pressure to create images. Three commonly used of Nonimpact Printer are Ink-jet printer, Laser printer, and Thermal printer. Ink-jet printer form characters and graphics by spraying tiny drops of liquid ink onto a piece of paper. Laser printer a high speed, high quality nonimpact printer. also for personal computers usually us individual sheets of paper stored in a removable tray that slides into the printer case. Thermal printer generates images by pushing electrically heated pins against heat sensitive paper. there are two special types of thermal printer, Thermal wax-transfer printer and Thermal transfer printer, generates rich, non-smearing images by using heat to melt color-wax onto heat-sensitive paper. Portable printer a small, lightweight printer that allows mobile user to print from a laptop or handheld computer while traveling. Plotters and Large-formal printer sophisticated printer used to produce high quality drawing such as blueprints, maps, circuit diagrams, and signs. Two basic types of plotters are Pen plotters and Electrostatic plotters. Pen plotters uses one or more color pen light beams. Electrostatic plotter uses a row of charged wires called styli to draw an electrostatic pattern on specially coated paper and then fuses toner to the pattern. |
