A printer is a device that accepts electronic data from a computer and prints it onto a physical medium, such as paper. In general, it is used for output from a software application, such as word processors and image editing programs, but it can also be used to print documents from the web, email, and so on.
There is an enormous amount of printing that goes on in the world. The obvious examples include books, newspapers, and magazines, but there is a lot of other printing, including business cards, postcards, brochures, catalogs, envelopes, folders, and the like. There is also a great deal of printing that is done for financial purposes, including checks, postage stamps, stock certificates and cerrtificates of deposit, as well as all kinds of legal documents.
Printers are usually very expensive and require a large amount of energy to operate, but they are necessary for much of what we do in the modern world. Many people find them frustrating and inconvenient, but they are useful for a number of tasks. In order to make them more useful, it is important to understand how they work.
The most common type of printer is the inkjet printer. An inkjet printer uses a nozzle that sprays a layer of liquid ink onto the paper. There are several different types of ink, but the most popular is dye based ink. Dye based inks are expensive and can contain hazardous chemicals. There are also solid ink printers that use a phase-change material similar to how a capacitor works, but these can only print monochrome.
