Printer and Printing Technology TechnologyThe printer is a hardware output device (hardware) that prints text or illustrations on paper adan other print media are possible. Currently there are different kinds of printers.
Based on the technology used, the printer can fall into the following:
1. Daisy-wheel: Similar to a typewriter that save a plastic or metal (such as hammer), which is printed every letter that will print the letter by pressing a ribbon. Ink-jet printers can print only letters and no graphics.
2. Dot-matrix: Creates characters by striking pins against an ink ribbon. Each pin makes a dot, and combinations of dots form characters and illustrations.
3. Ink-jet: Sprays ink on a sheet of paper. Ink-jet printers can produce text and graphics with high quality.
4. Laser: This printer uses the same technology as copy machines. These printers can produce text and graphics with a very high quality.
5. LCD & LED: This printer is similar to a laser printer, but uses liquid crystals (liquid crystals) or light emitting diodes (light-emitting diodes).
6. Line printer: Contains a chain of characters or pins that print an entire line at a time. This printer is very fast but with low quality.
7. Thermal printers: These printers use heated pins which are pressed with heat sensitive paper. These printers are widely used in calculators and fax machines.
The printer can also be classified based on the following characteristics.
1. The quality of mold or mold that is the output generated by the printer.
2. Print speed is measured in characters per second, or pages per minute.
3. Impact or non-impact related to the working system printers. Printer technology with a daisy-wheel, dot-matrix, and line printers are impact printers, but printers with laser technology and ink-jet is non-impact printers. The second important difference is the type of printer kegaduhannya. Impact printer is more noisy than the non-impact printers.
4. Print capabilities associated with text and graphics. Some printers can print only text and others can print text and graphics.
5. Font or typeface that can be printed. For example, dot-matrix printers can print only a few fonts. In contrast, laser printers and ink-jet printers capable of printing fonts are almost unlimited.
