Printing is a process of converting information stored on the computer into hard copy which can be read by a human. This is one of the most important output devices of a computer system.
Printers are categorized into different types depending on their printing features and functions. These include inkjet, laser, and dot-matrix printers.
Inkjet Printers: These are the most common printers that use a cartridge filled with ink to create a print. This type of printer can produce high-quality prints at a low cost.
Laser Printers: These are more expensive and can only be found in offices. These printers are able to create very fine, precise lines and can also be used to produce high-quality photographs.
Dot-matrix Printers: These printers are less expensive and are primarily found in home computers. They are less accurate than inkjet printers, but they are still useful.
Line Printers: These printers are very fast and can be used to print many pages at once. They are no longer widely used with personal computers, as they have been replaced by high-speed laser printers.
Plotters: These printers are used to print very large graphics. They can be either flatbed or drum plotters.
Solid Ink Printers: These printers are made from waxy, resin-based polymers. These polymers are melted through thermal technology to form solid sticks that are then sprayed onto a drum covered with oil to create a visual on the hard copy.
There are four factors to consider when choosing a printer: speed, memory, resolution, and paper capacity. These are all important when you need to make a lot of prints.
