A port is used to connect computers to peripheral (accessory) devices. It is very important to determine the point of sale peripherals that will be connected to each computer so you can plan your use of its ports. Here are the ports that you need to be aware of for your point of sale system:

A parallel port (also called a printer port) is used for connecting a printer to a computer. Parallel ports will normally have a picture of a printer next to it on the back of the computer. Parallel ports have a design limitation that requires a cable of no more than 9 to 12 feet. Use a parallel port to connect a printer to a computer that will sit beside the computer. Parallel printers are not normally appropriate for use as a remote printer in the kitchen.

A serial port (also called an RS-232 port) is used for several types of devices. Touch screens commonly have a serial connector to communicate screen touches to the computer. Point of sale printers are available with serial connectors. Customer displays (also called pole displays) normally use serial ports. The Point of Success Caller ID box requires a serial port. Computers commonly come with only one serial port, so plan your use of serial devices carefully. A serial cable can be up to 150 feet in length when it is constructed with high-quality cable, making a serial printer appropriate for use as a remote kitchen printer.

A USB port (Universal Serial Bus) can be used for printers, touch screens, and any other type of peripheral that incorporates a USB connection. The maximum USB cable length is 5 meters (16.5 feet). Cable length can be extended through the use of a powered USB hub.

An Ethernet port is used to connect a computer or peripheral device to a network. Point of sale printers are also available with Ethernet ports, making these printer models a good choice for a remote printer.
