For non-PostScript ( raster ) printers, the final raster image was produced by the computer and sent to the printer, which meant dot-matrix printers on the Mac platform exclusively used raster (" graphics ") printing mode.

* The Philips DCC-822 car stereo had a full dot-matrix text display which could display upper case and lower case titles from prerecorded tapes as well as super-user tapes

A number of trains were then modified for use on the Merseyside PTE city lines around Liverpool, which included dot-matrix route indicators, improved seating and Merseyrail PTE paintwork.

Demand for Chinese characters led to 20-bit Unicode, which clearly is impossible for any typewriter like formed character mechanical teleprinter, although dot-matrix printers can print Chinese characters.

However after this time, many trains intended to run over Southern Region lines were designed to display the numeric route-code portion of the train reporting number at the head of train, which they still display to this day, usually on dot-matrix displays.

Type 3 allowed unrestricted use of the PostScript language, but didn't include any hint information, which could lead to visible rendering artifacts on low-resolution devices ( such as computer screens and dot-matrix printers ).

The three primary methods of producing pairwise alignments are dot-matrix methods, dynamic programming, and word methods ; however, multiple sequence alignment techniques can also align pairs of sequences.

In the Philippines, for example, as early as 900AD, specimen documents were not inscribed by stylus, but were punched much like the style of today's dot-matrix printers.

The Apple Macintosh system was originally designed so that the screen resolution and the resolution of the ImageWriter dot-matrix printers sold by Apple were easily scaled: 72 PPI for the screen and 144 DPI for the printers.

In comparison with the laser printer, most inkjet printers and dot-matrix printers simply take an incoming stream of data and directly imprint it in a slow lurching process that may include pauses as the printer waits for more data.

Yet the dot-matrix print head was well-suited to this task, and the capability, referred to as " dot-addressable " quickly became a standard feature on all dot-matrix printers intended for the personal and home computer markets.

Hence, the color dot-matrix was suitable for abstract illustrations and piecharts, but not for photo-realistic reproduction.

Full-size dot-matrix impact printers are still used to print multi-part stationery, for example at bank tellers and auto repair shops, and other applications where use of tractor feed paper is desirable such as data logging and aviation.

The ink ribbon also does not easily dry out, including both the ribbon stored in the casing as well as the portion that is stretched in front of the print head ; this unique property allows the dot-matrix printer to be used in environments where printer duty can be rare, for instance, as with a Fire Alarm Control Panel's output.

This system was the first in the world to be placed in an opera house with " each screen ( having ) a switch to turn it off, a filter to prevent the dim, yellow dot-matrix characters from disturbing nearby viewers and the option to display texts in multiple languages for newer productions ( currently Spanish and German ).

However special " skytyping " techniques have been developed to write in the sky in a dot-matrix fashion, and are legible for longer despite the inevitable blurring effect caused by wind.

A seven-segment display ( SSD ), or seven-segment indicator, is a form of electronic display device for displaying decimal numerals that is an alternative to the more complex dot-matrix displays.

There are also fourteen-segment displays and sixteen-segment displays ( for full alphanumerics ); however, these have mostly been replaced by dot-matrix displays.

* R142 cars have a dot-matrix LCD route number display and mosaic LCD destination on the side destination signs, while R-142A cars have a mosaic LCD for both the route and destination on the side destination signs.

The scoreboard is in full LED and is four-sided, whereas the old scoreboard was eight-sided and featured alternating static dot-matrix displays ( very much outdated for today's standards ) and full color video displays.

Such displays were very common on pinball machines for displaying the score and other information, before the widespread use of dot-matrix display panels.

Before the advent of inexpensive dot-matrix displays, sixteen and fourteen-segment displays were some of the few options available for producing alphanumeric characters on calculators and other embedded systems.

Such displays were very common on pinball machines for displaying the score and other information, before the widespread use of dot-matrix display panels.

* CKD T5C5K: CKD T5C5K is an upgraded version of the T5C5, with dot-matrix displays for informing passengers.

Beyond the manual labor of type-ins, it was not uncommon for certain magazines to print poor quality listings, presenting the reader with nearly illegible characters ( especially in the case where machine-code data was printed using extended ASCII glyphs instead of DATA statements ); this typically happened when transferring the list output from the era's ubiquitous 7 – 8-pin dot-matrix printers directly to the printing presses — sometimes even without prettyprinting.

In the absence of noise, it can be easy to visually identify certain sequence features — such as insertions, deletions, repeats, or inverted repeats — from a dot-matrix plot.

The advantage of dot-matrix over other impact printers is that they can produce graphical images in addition to text ; however the text is generally of poorer quality than impact printers that use letterforms ( type ).

To construct a dot-matrix plot, the two sequences are written along the top row and leftmost column of a two-dimensional matrix and a dot is placed at any point where the characters in the appropriate columns match — this is a typical recurrence plot.

It was unique in that it provided libraries of clip-art and templates through a simple interface to build signs, posters and banners with household dot-matrix printers.

For many applications, dot-matrix LCDs have largely superseded LED displays, though even in LCDs 7-segment displays are very common.

The heating elements are usually arranged as a matrix of small closely spaced dots — thermal printers are actually dot-matrix printers, though they are not so called.

The charts generally look like highly pixellated cartoon drawings, in this sense resembling dot-matrix computer graphics or needlepoint patterns ( though usually without the colour nuance of the latter ).

NLQ became a standard feature on all dot-matrix printers.

However, the high common recognition factor of 7-segment displays, and the comparatively high visual contrast obtained by such displays relative to dot-matrix digits, makes seven-segment multiple-digit LCD screens very common on basic calculators.

Shatter was initially drawn on a first-generation Mac using a mouse and printed on a dot-matrix printer.

The Shatter artwork was initially drawn on a first-generation Apple Macintosh using a mouse, and printed out on an Apple dot-matrix ImageWriter.

In these, digits are often composed of large dot-matrix or seven-segment displays made of incandescent bulbs, light-emitting diodes, or electromechanical flip segments.

During the declining years of the mimeograph, some people made stencils with early computers and dot-matrix impact printers.

Such printer support was very strong with daisy-wheel and dot-matrix printers, but did not take much advantage of the development of PostScript fonts and laser printers.

Like plotters, laser printers offer high quality line art, and like dot-matrix printers, they are able to generate pages of text and raster graphics.

Later models introduced innovations such as spell-checking programs, increased formatting options, and dot-matrix printing.

With the introduction of third-party dot-matrix printers as well as laser printers and multisync monitors, resolutions deviated from even multiples of the screen resolution, making true WYSIWYG harder to achieve.

* PCW8256 ( Z80, 3. 5 MHz, 256 KB RAM, single 180 KB 3 " floppy drive, dot-matrix printer, green screen )

* PcW9256 ( Z80, 3. 5 MHz, 256 KB RAM, single 720 KB 3. 5 " floppy drive, dot-matrix printer, " paper white " screen )

Because far less printhead motion was involved than in a conventional dot matrix printer, these printers were much faster than dot matrix printers and were competitive in speed with formed-character line printers while also being able to print dot-matrix graphics as well as variable-sized characters.

When compared to the crisp typewriter quality of a daisy-wheel printer, the dot-matrix printer's legibility appeared especially bad.

In office applications, output quality was a serious issue, as the dot-matrix text's readability would rapidly degrade with each photocopy generation.

Ironically, whereas the daisy-wheel printer and pen-plotter struggled to reproduce bitmap images, the first dot-matrix impact printers ( including the MX-80 ) lacked the ability to print graphics.

Several manufacturers implemented color dot-matrix impact printing through a multi-color ribbon.

Text quality was a recurring issue with dot-matrix printers.

Near Letter Quality mode — informally specified as almost good enough to be used in a business letter — endowed dot-matrix printers with a simulated typewriter-like quality.

By the mid-1990s, inkjet technology had surpassed dot-matrix in the mainstream market.
