Parallel port cards are devices that allow computers to connect to the parallel port. Ideally, these cards can be used in both desktop and laptop computers, allowing for a variety of devices to be connected such as printers, scanners, external drives, and more. The cards are typically designed to be compatible with the latest form of parallel ports which include the Enhanced Parallel Port (EPP) and the Extended Capabilities Port (ECP).
The parallel port was first introduced by IBM in 1981 as an alternative to the older serial ports that had been used to connect peripherals to computers. The main advantage of the parallel port over the older serial ports was its dramatically increased data transfer rates of up to 4 megabits per second. Despite this increased speed, the parallel port is still significantly slower than other modern computer communication ports such as USB and FireWire.
A common use of parallel port cards is to connect printer devices to computers. Most of the newer inkjet and laser printers are designed to use the parallel port as standard. The most popular type of parallel card is the IEEE 1284-Compliant Parallel Card which is designed to provide data transfer speeds up to 1.5 megabits per second. Other types of parallel cards are available for specific applications and some cards are designed to work with multiple types of devices, allowing for maximum versatility. For example, some cards come with additional features such as connectors for parallel ports, serial ports and USB ports.
In general, parallel port cards are easy to install and usually require no additional software or drivers. The cards are usually designed to work with most operating systems and configurations. However, it is important to check the manufacturer's specifications before choosing a card as some cards have particular requirements.
The speed and convenience of modern computer ports such as USB have made the parallel port largely obsolete. However, the parallel port still remains a necessary connection for many printers and other devices. Parallel port cards can provide an effective solution for connecting these devices to the newest computers and laptops.
