94 | GlossaryLEDA Light-Emitting Diode (LED) is a semiconductor device that indicatesthe status of a printer.MAC addressMedia Access Control (MAC) address is a unique identifier associatedwith a network adapter. MAC address is a unique 48-bit identifier usuallywritten as 12 hexadecimal characters grouped in pairs (e. g., 00-00-0c-34-11-4e). This address is usually hard-coded into a Network InterfaceCard (NIC) by its manufacturer, and used as an aid for routers trying tolocate printers on large networks.MFPMulti Function Peripheral (MFP) is an office printer that includes thefollowing functionality in one physical body, so as to have a printer, acopier, a fax, a scanner and etc.MHModified Huffman (MH) is a compression method for decreasing theamount of data that needs to be transmitted between the fax printers totransfer the image recommended by ITU-T T.4. MH is a codebook-based run-length encoding scheme optimized to efficiently compresswhite space. As most faxes consist mostly of white space, thisminimizes the transmission time of most faxes.MMRModified Modified READ (MMR) is a compression methodrecommended by ITU-T T.6.ModemA device that modulates a carrier signal to encode digital information,and also demodulates such a carrier signal to decode transmittedinformation.MRModified Read (MR) is a compression method recommended by ITU-TT.4. MR encodes the first scanned line using MH. The next line iscompared to the first, the differences determined, and then thedifferences are encoded and transmitted.NetWareA network operating system developed by Novell, Inc. It initially usedcooperative multitasking to run various services on a PC, and thenetwork protocols were based on the archetypal Xerox XNS stack.Today NetWare supports TCP/IP as well as IPX/SPX.OPCOrganic Photo Conductor (OPC) is a mechanism that makes a virtualimage for print using a laser beam emitted from a laser printer, and it isusually green or gray colored and a cylinder shaped.An exposing unit of a drum is slowly worn away by its usage of theprinter, and it should be replaced appropriately since it gets scratchesfrom grits of a paper.OriginalsThe first example of something, such as a document, photograph or text,etc, which is copied, reproduced or translated to produce others, butwhich is not itself copied or derived from something else.OSIOpen Systems Interconnection (OSI) is a model developed by theInternational Organization for Standardization (ISO) for communications.OSI offers a standard, modular approach to network design that dividesthe required set of complex functions into manageable, self-contained,functional layers. The layers are, from top to bottom, Application,Presentation, Session, Transport, Network, Data Link and Physical.PABXA private automatic branch exchange (PABX) is an automatic telephoneswitching system within a private enterprise.PCLPrinter Command Language (PCL) is a Page Description Language(PDL) developed by HP as a printer protocol and has become anindustry standard. Originally developed for early inkjet printers, PCL hasbeen released in varying levels for thermal, matrix printer, and pageprinters.PDFPortable Document Format (PDF) is a proprietary file format developedby Adobe Systems for representing two dimensional documents in adevice independent and resolution independent format.PostScriptPostScript (PS) is a page description language and programminglanguage used primarily in the electronic and desktop publishing areas. -that is run in an interpreter to generate an image.Printer DriverA program used to send commands and transfer data from the computerto the printer.Print MediaThe media like paper, envelopes, labels, and transparencies which canbe used on a printer, a scanner, a fax or, a copier.PPMPages Per Minute (PPM) is a method of measurement for determininghow fast a printer works, meaning the number of pages a printer canproduce in one minute.PRN fileAn interface for a device driver, this allows software to interact with thedevice driver using standard input/output system calls, which simplifiesmany tasks.ProtocolA convention or standard that controls or enables the connection,communication, and data transfer between two computing endpoints.PSSee PostScript.PSTNThe Public-Switched Telephone Network (PSTN) is the network of theworld's public circuit-switched telephone networks which, on industrialpremises, is usually routed through the switchboard.ResolutionThe sharpness of an image, measured in Dots Per Inch (DPI). Thehigher the dpi, the greater the resolution.SMBServer Message Block (SMB) is a network protocol mainly applied toshare files, printers, serial ports, and miscellaneous communicationsbetween nodes on a network. It also provides an authenticated Inter-process communication mechanism.SMTPSimple Mail Transfer Protocol (SMTP) is the standard for e-mailtransmissions across the Internet. SMTP is a relatively simple, text-based protocol, where one or more recipients of a message arespecified, and then the message text is transferred. It is a client-serverprotocol, where the client transmits an email message to the server.
