MFP
Multi Function Peripheral (MFP) is an office machine that includes the following functionality in one physical body,
so as to have a printer, a copier, a fax, a scanner and etc.
MH
Modified Huffman (MH) is a compression method for decreasing the amount of data that needs to be transmitted
between the fax machines to transfer the image recommended by ITU-T T.4. MH is a codebook-based run-length
encoding scheme optimized to efficiently compress white space. As most faxes consist mostly of white space, this
minimizes the transmission time of most faxes.
MMR
Modified Modified READ (MMR) is a compression method recommended by ITU-T T.6.
Modem
A device that modulates a carrier signal to encode digital information, and also demodulates such a carrier signal
to decode transmitted information.
MR
Modified Read (MR) is a compression method recommended by ITU-T T.4. MR encodes the first scanned line using
MH. The next line is compared to the first, the differences determined, and then the differences are encoded and
transmitted.
NetWare
A network operating system developed by Novell, Inc. It initially used cooperative multitasking to run various
services on a PC, and the network protocols were based on the archetypal Xerox XNS stack. Today NetWare
supports TCP/IP as well as IPX/SPX.
OPC
Organic Photo Conductor (OPC) is a mechanism that makes a virtual image for print using a laser beam emitted
from a laser printer, and it is usually green or gray colored and a cylinder shaped.
An exposing unit of a drum is slowly worn away by its usage of the printer, and it should be replaced
appropriately since it gets scratches from grits of a paper.
Originals
The first example of something, such as a document, photograph or text, etc, which is copied, reproduced or
translated to produce others, but which is not itself copied or derived from something else.
OSI
Open Systems Interconnection (OSI) is a model developed by the International Organization for Standardization
(ISO) for communications. OSI offers a standard, modular approach to network design that divides the 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.
PABX
A private automatic branch exchange (PABX) is an automatic telephone switching system within a private
enterprise.
PCL
Printer Command Language (PCL) is a Page Description Language (PDL) developed by HP as a printer protocol
and has become an industry standard. Originally developed for early inkjet printers, PCL has been released in
varying levels for thermal, matrix printer, and page printers.
Portable Document Format (PDF) is a proprietary file format developed by Adobe Systems for representing two
dimensional documents in a device independent and resolution independent format.
