EtherTalk
A suite of protocols developed by Apple Computer for computer networking. It was included in the original Mac (1984) and is
now deprecated by Apple in favor of TCP/IP networking.
FDI
Foreign Device Interface (FDI) is a card installed inside the machine to allow a third party device such as a coin operated
device or a card reader. Those devices allow the pay-for-print service on your machine.
FTP
A File Transfer Protocol (FTP) is a commonly used protocol for exchanging les over any network that supports the TCP/IP
protocol (such as the Internet or an intranet).
Fuser Unit
The part of a laser printer that fuses the toner onto the print media. It consists of a heat roller and a pressure roller. After
toner is transferred onto the paper, the fuser unit applies heat and pressure to ensure that the toner stays on the paper
permanently, which is why paper is warm when it comes out of a laser printer.
Gateway
A connection between computer networks, or between a computer network and a telephone line. It is very popular, as it is a

IEEE
The Institute of Electrical and Electronics Engineers (IEEE) is an international non-prot, professional organization for the
advancement of technology related to electricity.
IEEE 1284
The 1284 parallel port standard was developed by the Institute of Electrical and Electronics Engineers (IEEE). The term
"1284-B" refers to a specic connector type on the end of the parallel cable that attaches to the peripheral (for example, a
printer).
Intranet
A private network that uses Internet Protocols, network connectivity, and possibly the public telecommunication system to

most visible service, the internal website.
IP address
An Internet Protocol (IP) address is a unique number that devices use in order to identify and communicate with each other
on a network utilizing the Internet Protocol standard.
IPM
The Images Per Minute (IPM) is a way of measuring the speed of a printer. An IPM rate indicates the number of single-sided
sheets a printer can complete within one minute.
IPP
The Internet Printing Protocol (IPP) denes a standard protocol for printing as well as managing print jobs, media size,
resolution, and so forth. IPP can be used locally or over the Internet to hundreds of printers, and also supports access
control, authentication, and encryption, making it a much more capable and secure printing solution than older ones.
