What is standard parallel port?
A standard parallel port (SPP) is a port for connecting various relatively high bandwidth peripherals, most commonly printers, to a PC. Later versions of the SPP allow duplex communication. They use the DB-25 connector. This term is also known as parallel port, printer port, Centronics port or Centronics interface.
Are parallel printer cables still used?
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-compatible computers.
What is the use of 25-pin parallel port?
On PCs, the parallel port uses a 25-pin connector (type DB-25) and is used to connect printers, computers and other devices that need relatively high bandwidth. It is often called a Centronics interface after the company that designed the original standard for parallel communication between a computer and printer.
What is a parallel port on a printer?
The parallel port is found on the back of IBM compatible computers and is a 25-pin (type DB-25) computer interface commonly used to connect printers to the computer. …
What is the recommended maximum length for a parallel cable?
Given that reliable parallel port operation limits one to a cable length of no more than 15 feet, network print servers make a lot more sense.
What is the 36 pin parallel port?
Parallel port cables used for printing often have an even larger 36-pin “Centronics 36” connector that connects to the printer. The original parallel port standard was unidirectional and could transmit data at a maximum speed of 150 kbps.
Is USB serial or parallel?
While interfaces such as Ethernet, FireWire, and USB also send data as a serial stream, the term serial port usually denotes hardware compliant with RS-232 or a related standard, such as RS-485 or RS-422.
What can I do with a parallel port?
(2) A socket on a computer used to connect a printer or other device via a parallel interface (eight data bits transferring simultaneously). In the past, the parallel port was widely used for printers and occasionally for connecting other devices externally, but was superseded by USB.
What is the other name of parallel port?
This standard defined bi-directional parallel communication between computers and other peripheral devices allowing data bits to be transmitted and received simultaneously. This term is also known as a Centronics port or printer port and has now been largely superseded by the USB interface.
What printer cable uses a male DB 25 connector to attach to the PC?
Printer-cable meaning A cable that connects a printer to a computer. On a PC, it typically refers to a cable with a 25-pin DB-25 male connector that plugs into the computer and a 36-pin Centronics male connector that plugs into the printer. Known as a “Centronics” cable, it uses the parallel port on the computer.
How fast is a USB port?
USB Standards

What is the difference between LPT port and COM port?
LPT is a parrallel port typically associated with old printers. COM is a serial port assiciated with older interace devices like mice, PDAs, etc.
