The mechanism of the matrix printer

THE MECHANISM OF THE MATRIX PRINTER

A printer is a device designed to print information from a computer to paper or, as they say in a "computer" language, to a hard drive. In this case, the process of transferring information is called printing, and the resulting document-printing.

Names of printers today already hundreds, and maybe, and thousands. They differ in the principle of operation, the number of colors, the type of ink and printed material, the purpose – in General, all and not counted. And each of these types can still have their own characteristics and additional functions. Today, the so-called multifunctional devices (MFPs), which combine a printer, a scanner, a copier, and even a Fax, are widely used.

The mechanism of the matrix printer (the oldest type of printing devices used today) was invented by the Japanese in 1964.

The principle of its operation, in General, is simple. The image on the sheet is created using the print head, consisting of a set of needles (matrix), which are driven by electromagnets. The head moves line by line along the sheet of paper, and the needles hit it through the coloring tape, leaving an imprint-a point image.

Inkjet printer

The principle of operation of the inkjet printer is similar to the action of the matrix: the image is created from points. Only instead of heads with needles they use a matrix (head), which prints with liquid dyes.

The print head can be embedded in the ink cartridge or attached to the machine.

Laser printer

Laser technology (and to be precise – electrographic technology) appeared in 1938. This method of printing, called first electrography, then-xerography, and today more commonly known as laser printing, different speed, efficiency and high quality print.

The main part of the device is the so-called drum, which retains on the surface of the electric charge, and it is "his" at each point. Laser beam, getting on the drum, "illuminates" individual points of the drum, removing them from the charge. By controlling the beam, you can "draw" on the drum charged and uncharged areas. Particles of a special composition. Wake up on the drum and stick only to the charged points, thus forming an image.
