ECP/EPP has two advantages over SPP. When your computer is in ECP/EPP
mode, you can print documents faster than when the computer is in SPP mode, and
you can attach devices other than printers, such as communication and storage
devices, to the parallel port. You can set modes of operation for the parallel port
using the Configuration/Setup Utility program.
Note: To minimize electromagnetic interference (EMI), use braid-shielded cables
with metal ends when connecting a device to the parallel port.
Serial ports
Your computer has two standard 16550-UART serial ports that can be used to
communicate with devices such as modems, plotters, and printers.
Note: To minimize electromagnetic interference (EMI), use braid-shielded cables
with metal ends when connecting devices to these ports.
Universal Serial Bus ports
The universal serial bus (USB) interface is a state-of-the-art technology developed to
add more diversity and capabilities to personal computers. As a standard feature,
your computer has two USB ports, so you can take advantage of new USB devices
as they become available.
Using this new technology, you can plug different types of optional,
USB-compatible devices into the USB ports on your computer. Because USB
incorporates Plug and Play technology, you can install and remove devices easily
without turning off your computer or opening the cover. Once installed, the
devices configure automatically. In addition, an option called a hub can be
connected to a USB port on your computer, which enables you to plug in more than
one device at a time. A hub converts a single USB connector into multiple ports
where USB devices can be attached.
