Dot-matrix Printer
Dot matrix printing, sometimes called impact matrix printing, is a computer printing process in which ink is applied to a surface using a relatively low-resolution dot matrix for layout. Dot matrix printers are a type of impact printer that prints using a fixed number of pins or wires and typically use a print head that moves back and forth or in an up-and-down motion on the page and prints by impact, striking an ink-soaked cloth ribbon against the paper. They were also known as serial dot matrix printers. Unlike typewriters or line printers that use a similar print mechanism, a dot matrix printer can print arbitrary patterns and not just specific characters. The perceived quality of dot matrix printers depends on the vertical and horizontal resolution and the ability of the printer to overlap adjacent dots. 9-pin and 24-pin are common; this specifies the number of pins in a specific vertically aligned space. With 24-pin printers, the horizontal movement can slightly overlap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hellschreiber
The Hellschreiber, Feldhellschreiber or Typenbildfeldfernschreiber (also Hell-Schreiber named after its inventor Rudolf Hell) is a fax, facsimile-based teleprinter invented by Rudolf Hell. Compared to contemporary teleprinters that were based on typewriter systems and were mechanically complex and expensive, the Hellschreiber was much simpler and more robust, with far fewer moving parts. It has the added advantage of being capable of providing intelligible communication even over very poor quality radio or cable links, where voice or other teledata would be unintelligible. The device was first developed in the late 1920s, and saw use starting in the 1930s, chiefly being used for landline press services. During World War II it was sometimes used by the Wehrmacht, German military in conjunction with the Enigma machine, Enigma encryption system. In the post-war era, it became increasingly common among newswire services, and was used in this role well into the 1980s. Today, the Hel ...

Epson MX-80
The MX-80 is a serial dot matrix printer introduced by Seiko Epson in 1980. The MX-80 is capable of printing a maximum of 132 columns per line, while its 9-pin printhead was the first disposable, user-serviceable printhead on the market. The MX-80 was a massive commercial success for Epson and soon became the best-selling dot matrix printer in the world, selling well over one million units over the course of its market lifespan. It enjoyed a high level of popularity in the personal computer marketplace for much of the 1980s and was the progenitor of the ESC/P printer control language. The form factor and basic functionality of the MX-80 soon became a ''de facto'' standard for manufacturers of inexpensive dot matrix printers. Epson released a number of succeeding revisions of the MX-80 before replacing the entire line with the FX-80 in 1983. Background and development Seiko Epson (known as Shinshu Seiki until 1975) entered the market for computer printers with the EP ...

Transistorized
A transistor is a semiconductor device used to amplify or switch electrical signals and power. It is one of the basic building blocks of modern electronics. It is composed of semiconductor material, usually with at least three terminals for connection to an electronic circuit. A voltage or current applied to one pair of the transistor's terminals controls the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Some transistors are packaged individually, but many more in miniature form are found embedded in integrated circuits. Because transistors are the key active components in practically all modern electronics, many people consider them one of the 20th century's greatest inventions. Physicist Julius Edgar Lilienfeld proposed the concept of a field-effect transistor (FET) in 1925, but it was not possible to construct a working device at that time. The first ...

Deutsche Bundespost
The (, ) was a German state-run postal service and telecommunications business founded in 1947. It was initially the second largest federal employer during its time. After staff reductions in the 1980s, the staff was reduced to roughly 543,200 employees in 1985. The corporation was dissolved in 1995 under two rounds of postal reforms that took place in the German Post Office in 1989 and 1995, respectively. Following the reforms, the former was broken into three publicly traded corporations: Deutsche Post AG (postal services), Deutsche Telekom (telecommunications), and Deutsche Postbank AG (banking). History Created in 1947 in the Trizone as a successor to the '' Deutsche Reichspost'' (German Imperial Post), until 1950 the enterprise was called ''Deutsche Post'' (German Post). Until 1989, the ''Deutsche Bundespost'' was a state-owned operation. Organization The ''Bundespost'' was developed according to a three-tier principle common in public administration in the Fed ...

Synchronous Transmission
Synchronous serial communication describes a serial communication protocol , "In synchronous transmission, groups of bits are combined into frames,and frames are sent continuously with or without data to be transmitted." Synchronous communication requires that the clocks in the transmitting and receiving devices are ''synchronized'' – running at the same rate – so the receiver can sample the signal at the same time intervals used by the transmitter. No start or stop bits are required. For this reason "synchronous communication permits more information to be passed over a circuit per unit time" than asynchronous serial communication. Over time the transmitting and receiving clocks will tend to drift apart, requiring ''resynchronization''. Synchronous RS-232 used additional pins on the DB-25 cable: the DCE (generally the modem or other peripheral) provided two clock signals to the DTE (generally the host computer or terminal), transmitter clock (pin 15, TCK) and rece ...

Asynchronous Transmission
Data communication, including data transmission and data reception, is the transfer of data, transmitted and received over a point-to-point or point-to-multipoint communication channel. Examples of such channels are copper wires, optical fibers, wireless communication using radio spectrum, storage media and computer buses. The data are represented as an electromagnetic signal, such as an electrical voltage, radiowave, microwave, or infrared signal. ''Analog transmission'' is a method of conveying voice, data, image, signal or video information using a continuous signal that varies in amplitude, phase, or some other property in proportion to that of a variable. The messages are either represented by a sequence of pulses by means of a line code (''baseband transmission''), or by a limited set of continuously varying waveforms (''passband transmission''), using a digital modulation method. The passband modulation and corresponding demodulation is carried out by modem equi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
