A parallel port is a type of interface found on computers personal and otherwise for connecting peripherals. The name refers to the way the data is sent parallel ports send multiple bits of data at once, in parallel communication, as opposed to serial interfaces that send bits one at a time. To do this, parallel ports require multiple data lines in their cables and port connectors, and tend to be larger than contemporary serial ports which only require one data line. There are many types of parallel ports, but the term has become most closely associated with the printer port or Centronics port found on most personal computers from the 1. It was an industry de facto standard for many years, and was finally standardized as IEEE 1. Enhanced Parallel Port EPP and Extended Capability Port ECP bi directional versions. Today, the parallel port interface is virtually non existent because of the rise of Universal Serial Bus USB devices, along with network printing using Ethernet and Wi Fi connected printers. The parallel port interface was originally known as the Parallel Printer Adapter on IBM PC compatiblecomputers. It was primarily designed to operate printers that used IBMs 8 bit extended ASCIIcharacter set to print text, but could also be used to adapt other peripherals. Graphical printers, along with a host of other devices, have been designed to communicate with the system. HistoryeditCentronicseditDr. An Wang, Robert Howard and Prentice Robinson began development of a low cost printer at Centronics, a subsidiary of Wang Laboratories that produced specialty computer terminals. The printer used the dot matrix printing principle, with a print head consisting of a vertical row of seven metal pins connected to solenoids. When power was applied to the solenoids, the pin was pulled forward to strike the paper and leave a dot. To make a complete character glyph, the print head would receive power to specified pins to create a single vertical pattern, then the print head would move to the right by a small amount, and the process repeated. On their original design, a typical glyph was printed as a matrix seven high and five wide, while the A models used a print head with 9 pins and formed glyphs that were 9 by 7. This left the problem of sending the ASCII data to the printer. While a serial port does so with the minimum of pins and wires, it requires the device to buffer up the data as it arrives bit by bit and turn it back into multi bit values. A parallel port makes this simpler, the entire ASCII value is presented on the pins in complete form. In addition to the seven data pins, the system also needed various control pins as well as electrical grounds. Wang happened to have a surplus stock of 2. Amphenol 3. 6 pin micro ribbon connectors that were originally used for one of their early calculators. The interface only required 2. The connector has become so closely associated with Centronics that it is now popularly known as the Centronics connector. The Centronics Model 1. The host sent ASCII characters to the printer using 7 of 8 data pins, pulling them high to 5. V to represent a 1. When the data was ready, the host pulled the STROBE pin low, to 0 V. Wireshark Tls Decrypt. The printer responded by pulling the BUSY line high, printing the character, and then returning BUSY to low again. The host could then send another character. Control characters in the data caused other actions, like the CR or EOF. The host could also have the printer automatically start a new line by pulling the AUTOFEED line high, and keeping it there. The host had to carefully watch the BUSY line to ensure it did not feed data to the printer too rapidly, especially given variable time operations like a paper feed. The printer side of the interface quickly became an industry de facto standard, but manufacturers used various connectors on the system side, so a variety of cables were required. For example, NCR used the 3. VAX systems used a DC 3. Texas Instruments used a 2. Data General used a 5. When IBM implemented the parallel interface on the IBM PC, they used the DB 2. F connector at the PC end of the interface, creating the now familiar parallel cable with a DB2. M at one end and a 3. In theory, the Centronics port could transfer data as rapidly as 7. This was far faster than the printer, which averaged about 1. The performance was defined by how rapidly the host could respond to the printers BUSY signal asking for more data. To improve performance, printers began incorporating buffers so the host could send them data more rapidly, in bursts. This not only reduced or eliminated delays due to latency waiting for the next character to arrive from the host, but also freed the host to perform other operations without causing a loss of performance.

Performance was further improved by using the buffer to store several lines and then printing in both directions, eliminating the delay while the print head returned to the left side of the page. Such changes well over doubled the performance of an otherwise unchanged printer, as was the case on Centronics models like the 1. IBM released the IBM Personal Computer in 1. Centronics interface only IBM logo printers rebranded from Epson could be used with the IBM PC. IBM standardized the parallel cable with a DB2. F connector on the PC side and the 3. Centronics connector on the printer side. Vendors soon released printers compatible with both standard Centronics and the IBM implementation. The original IBM parallel printer adapter for the IBM PC was designed to support 8 bit data bidirectionally in 1. This allowed the port to be used for other purposes, not just output to a printer. This was accomplished by allowing the data lines to be written to by devices on either end of the cable, which required the ports on the host to be bidirectional. This feature saw little use, and was removed in later revisions of the hardware. Years later, in 1. IBM reintroduced the bidirectional interface with its IBM PS2 series, where it could be enabled or disabled for compatibility with applications hardwired not to expect a printer port to be bidirectional.
