1. Acquaint Yourself With Computer Printers A computer printer is a device used for printing text or images on hard copy stored in electronic form, generally on physical print media like paper. Printers are designed to support both local and network connected users simultaneously. Nowadays, modern printers can directly interface to electronic devices like digital cameras. Some printers that come with non printing features are commonly known as Multi-Functional Printers (MFP) or Multi-Function Devices (MFD). It integrates various functions of multiple devices into one. Such types of printers are extremely useful for small businesses and home offices. As opposed to a traditional printer, a multi-functional printer is a combination of devices like Printer, Scanner, Photocopier, and Fax Machine. Likewise, there are numerous other types of printers widely available in the market. Let's take a look at them: Laser Printer: A laser printer works in a similar fashion as a photocopier does. It has a roller which is charged with electricity. A laser beam is passed to remove the charge from portions of the roller. The parts hit by the laser are powdered by the toner which is then transferred from the roller to the paper. Finally, the ink is baked into the paper with the help of a heater incorporated in the printer. People generally prefer laser printer because of its ability to give high quality output and high speed. Dot Matrix: It has a print head that moves across the page. A dot matrix printer produces characters using a cluster of pins which press an inked ribbon to the paper, thereby creating a dot. Each character is made in the same way. Dot Matrix printers are relatively cheaper and durable. These qualities still attract businesses which use them as invoice printers. For more info - http://ctcopier.com/
