EspañolDOT MATRIX
(Redirected from Dot-matrix)
A 'dot matrix' is a 2-dimensional array of dots used to generate characters, symbols and images.
Typically the dot matrix is used in older computer printers and many digital display devices. In printers, the dots are usually the darkened areas of the paper. In displays, the dots may light up, as in an LED or CRT display, or darken, as in an LCD, however multicolor LCDs are sometimes initially dark and light up.
In the context of printers, the term mainly refers to impact printers, with a column of 8, 9 or 24 "pins" hitting an ink-impregnated fabric ribbon, like a typewriter ribbon, onto the paper. It was originally contrasted with daisy wheel printers and line printers.
Almost all modern computer printers also create their output as matrices of dots, but use a different technology like Laser printing or inkjet printing, and are not called Dot Matrix printers. Dot Matrix printers survive where multi-part forms are needed, as the impact can make a carbonless copy. For security purposes.
A dot matrix is useful for marking materials other than paper. In manufacturing industry, many marking applications use dot matrix inkjet or impact methods. This can also be used to print 2D matrix codes, e.g. Datamatrix.
