What is a parallel port connector?
A parallel port is an interface allowing a personal computer (PC) to transmit or receive data down multiple bundled cables to a peripheral device such as a printer. The most common parallel port is a printer port known as the Centronics port.
How does a parallel port work on a computer?
When a PC sends data to a printer or other device using a parallel port, it sends 8 bits of data (1 byte) at a time. These 8 bits are transmitted parallel to each other, as opposed to the same eight bits being transmitted serially (all in a single row) through a serial port.
Which devices use parallel ports?
Parallel ports can be used to connect a host of popular computer peripherals:
- Printers.
- Scanners.
- CD burners.
- External hard drives.
- Iomega Zip removable drives.
- Network adapters.
- Tape backup drives.
Why is the parallel port important?
Parallel ports provide an interface to connect multiple lines to prepare a parallel communication to send large data at a time. Parallel ports are used in connecting printers, hard-drives, CD-drives etc. All lines speed should be same to avoid error and cross-talk issues.
Where is parallel port connected?
The Apple II Parallel Printer Port connected to the printer via a folded ribbon cable; one end connected to the connector at the top of the card, and the other end had a 36-pin Centronics connector….Parallel port.

What is parallel port and serial port?
A serial port is able to transmit a single stream of data at a time. A parallel port is able to transmit multiple data streams at a time.
What is the name of the parallel port?
A parallel port, also known as a Centronics port, Centronics interface, or Centronics connector, is an external interface that was used to connect peripheral devices such as printers.
What is the difference between parallel port and USB port?
Unlike a parallel port, which can connect one device at a time, USB ports can support additional devices with an external USB hub. A USB hub is plugged into a USB port on the computer and provides additional USB ports.

What are the features of parallel port?
Characteristics of Parallel Ports
- Transfer multiple bits at a time.
- It can send/receive 8 bits/1 byte at a time.
- It contains 25 female pins.
- Connects devices like printer, external HDD, scanners, etc. to the computer.
- The most common parallel port is the printer port.
- Data travel speed is 150 kilobits per second.
Does parallel USB adapter work?
Parallel-to-USB adapter work best with older computers that run DOS applications that don’t use the Windows Print Spooler to process print jobs. Parallel-to-USB adapters usually require an external power supply to function properly, and do not support high-speed USB connections.
How do I connect USB to parallel?
Windows recognizes the printer using the adapter cable.
- Plug the printer’s power cord into an outlet, but keep the printer turned off.
- Plug the parallel connector of the parallel-to-USB adapter cable into the parallel port on the printer.
- Plug the USB connector into a free USB port on the computer.
- Turn on the computer.
How do I connect a USB printer to a parallel port on my computer?
The USB to parallel printer cable allows your PC to print to most parallel printer device connected through the USB port. Just plug the USB connector of the cable into the USB port of your PC and the other end into the Centronics connector of the parallel printer.
