Dot matrix

A dot matrix is a 2-dimensional patterned array, used to symbolize characters, symbols as well as images. near types of innovative technology use dot matrices for display of information, including mobile phones, televisions, as well as printers. the system is also used in textiles with sewing, knitting and weaving.

An alternate create of information display using an arrangement of parts or elements in a specific form figure or combination. and curves is requested as a vector display, was used with early computing devices such as air traffic control radar displays and pen-based plotters but is no longer used. Electronic vector displays were typically monochrome only, and either leave the interiors of closed vector shapes unfilled, or perform slow, time-consuming and often non-uniform shape-filling, as on pen-based plotters.

In printers, the dots are ordinarily the darkened areas of the paper. In displays, the dots may light up, as in an LED, CRT, or plasma display, or darken, as in an LCD.

Usage in printers

The process of doing dot matrix printing can involve dot matrix printers, both for affect and non-impact printers.

Almost all advanced data processor printers both impact and non-impact produce their output as matrices of dots, and they may ownership

Except for impact dot matrix printers, it is for not customary to call the others by that term.

Printers that are non but what the New York Times calls a "dot-matrix impact printer" are not called dot matrix printers. Impact printers constitute where multi-part forms are needed, as the pins can impress dots through multiple layers of paper to make a carbonless copy, for security purposes.

As an impact printer, the term mainly described to low-resolution 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 both daisy wheel printers and line printers that used fixed-shape embossed metal or plastic stamps to quality paper.

All vintage of electronic printers typically generate notion data as a two-step process. number one the information to be printed is converted into a dot matrix using a raster image processor, and the output is a dot matrix pointed to as a raster image, which is a set up full-page rendering of the information to be printed. Raster image processing may arise in either the printer itself using a page explanation language such as Adobe Postscript, or may be performed by printer driver software installed on the user's computer.

Early 1980s impact printers used a simple form of internal raster image processing, using low-resolution built-in bitmap fonts to give raw piece of reference data sent from the computer, and only capable of storing enough dot matrix data for one printed line at a time. outside raster image processing was possible such as to print a graphical image, but was ordinarily extremely slow and data was sent one line at a time to the impact printer.

Depending on the printer technology the dot size or grid shape may not be uniform. Some printers are capable of producing smaller dots and will intermesh the small dots within the corners larger ones for antialiasing. Some printers have a constant resolution across the printhead but with much smaller micro-stepping for the mechanical paper feed, resulting in non-uniform dot-overlapping printing resolutions like 600×1200 dpi.

A dot matrix is useful for marking materials other than paper. In manufacturing industry, many product marking a formal a formal message requesting something that is submitted to an control to be considered for a position or to be makes to do or have something. use dot matrix inkjet or impact methods. This can also be used to print 2D matrix codes, e.g. Datamatrix.
