An '''MFP''' ('''M'''ulti '''F'''unction '''P'''rinter/'''P'''roduct/'''P'''eripheral), '''multifunctional''', '''all-in-one''' (AIO), or '''Multifunction Device (MFD)''', is an office machine which incorporates the functionality of multiple devices in one, so as to have a smaller footprint in a home or [[small business]] setting (the [[Small office/home office|SOHO]] market segment), or to provide centralized document management/distribution/production in a large-office setting. A typical MFP may act as a combination of some or all of the following devices:
* [[Computer printer|Printer]]
* [[Image scanner|Scanner]]
* [[Photocopying|Photocopier]]
* [[Fax]]
* [[E-mail]]
MFP manufacturers/brands include [[Brother Industries|Brother]], [[Canon Inc.|Canon]], [[Dell Computer|Dell]], [[Epson]], [[Hewlett-Packard]], [[Konica Minolta]], [[Kyocera]], [[Lexmark]], [[Oce]], [[Okidata]], [[Olivetti]], [[Ricoh]], [[Samsung Electronics|Samsung]], [[Sharp Corporation|Sharp]], [[Toshiba]] and [[Xerox]]. Note that not all of these manufacturers produce all types of MFP - some may only focus on AIO products, whilst others may only focus on Production Printing, while yet more may cover a wider range.

MFP manufacturers traditionally divided MFPs in to various '''segments'''. The segments roughly divide the MFPs according to their speed in pages per minute (ppm). Despite this, many manufacturers are beginning to avoid the segment definition for their products, as speed and basic functionality alone are often not sufficient to differentiate the many features that the devices are capable of. Two color MFPs of a similar speed will be in the same segment, despite having potentially very different feature sets, and therefore very different prices. From a marketing perspective, the manufacturer of the more expensive MFP would want to differentiate their product as much as possible to justify the price difference, and therefore the segment definition is avoided.
Many MFP types, regardless of the category they fall in to, also come in a "printer only" variety, which is the same model without the scanner unit included. This is even the case with devices where the scanner unit physically appears to be highly integrated in to the product.
So, instead of rigidly defined segments based on speed, more general definitions based on intended target audience and capabilities are now becoming much more common. While there is no formal definition, it is common agreed amongst MFP manufacturers that the products fall roughly in to the following categories:
===AIO===
An AIO is a small desktop unit, designed for home or home office use.
Generally the features an AIO has focus on scan and print functionality for home use, and may come with bundled software for organising photos, simple OCR and other uses of interest to a home user. An AIO will always include the basic functions of Print and Scan, with most also including Copy functionality and a lesser number with Fax capabilities.
AIO devices are usually not networked and are generally connected by [[USB]] or [[IEEE1284|Parallel]].
An interesting note about AIO devices is that they often have features lacking in the larger devices, due to their target towards home users. These functions include smart card readers, direct connection to [[digital cameras]] (e.g. [[PictBridge]] technology) and other similar uses.
The print engine of most AIOs is based on either a home desktop [[inkjet printer]], or a home desktop [[laser printer]]. They may be be black and white or colour capable.
===SOHO MFP===
A large desktop or small freestanding unit, designed for Small Office/Home Office use. Often, the form factor of the MFP (desktop or freestanding) depends on the options added, such as extra paper trays or so on.
Generally a SOHO MFP will have basic Print, Copy, Scan and Fax functionality only, but towards the larger end of the scale, may include simple document storage and retrieval, basic authentication functions and so on, making the higher end of the "SOHO" scale difficult to differentiate from the lower end of the "Office" MFP scale.
SOHO MFPs are usually networked, however may also be connected via USB or, less frequently, parallel. SOHO MFPs may have basic finishing functionality such as duplexing, stapling and holepunching, however this is rare. In general, document output offset, sorting and collation are standard capabilities.
By comparison to an AIO, a SOHO MFP is more likely to have an automatic document feeder, greater fax capabilities and faster output performance.
Most SOHO MFPs have their history in low end black and white [[photocopier]]s, and the print engine is therefore based around this type of technology.
===Office MFP===
A mid-sized freestanding unit, designed as a central office system.
These units are usually the most fully featured type of MFP. They include the basic Print, Copy and Scan functions with optional fax functionality as well as networked document storage with security, authentication using common network user credentials, ability to run custom software (often a manufacturer will supply a [[Software Development Kit]]), advanced network scan destinations such as [[FTP]], [[WebDAV]], [[Email]], [[Server_Message_Block|SMB]] and [[Network_File_System_(protocol)|NFS]] stores, encryption for data transmission and so on.
Office MFPs usually have moderately advanced finishing functions as options such as duplexing, stapling, holepunching, offset modes and booklet creation.
Office MFPs are almost always networked, however some have optional or standard (but infrequently used) [[USB]] and [[IEEE 1284|parallel]] connections.
Most Office MFPs have their history in mid range [[photocopier]]s (both colour and black and white), and the print engine is therefore based around this type of technology, however, [[Hewlett-Packard]] recently introduced two Office MFPs based on fixed head Inkjet technology.
===Production Printing MFP===
A large sized freestanding unit, designed as a central printing device or reprographic department device.
These devices, while far larger and more expensive than Office MFPs, generally do not have all of the advanced network functionality of their smaller relations. They instead concentrate on high speed, high quality output, and highly advanced finishing functionality including book creation with cover insertion (including hot-glue binding) and so on. Production Printing itself is often further divided in to "light" production printing and "heavy" production printing, with the differentiating factor being the speed. A 100ppm device for example, falls in to the light Production Printing category by the standards of most manufacturers.
Because of the focus on printing, while most Production Printing MFPs have a scanner, it is infrequently used and often only has very basic functionality.
There are a variety of different print engines for Production Printing MFPs, however in the "light" end of the Production Printing market, most are based on the large Office MFPs, which themselves are based on [[photocopier]] technology as described above.
Production Printing MFPs may also be known as "Print on Demand" devices, or "Digital Presses". This latter term can also be used to refer to the [[print controller]] controlling the MFP however.
==Characteristics==
It is useful to consider the features and functions of an MFP before integrating it in to a home or office environment. It is possible to have an MFP with almost all of the features and functions listed below, however a typical AIO or SOHO MFP is unlikely to incorporate many of these.
An (incomplete) list of features that an MFP may offer or will vary depending on the MFP under consideration (in any segment):
===Print features/functions===
* '''Input'''
** [[Printer driver]]s available for different operating systems
** [[Page_description_language|PDL]]s ([[PostScript]], [[Printer_command_language|PCL]], [[XML_Paper_Specification|XPS]] etc) and direct interpreters ([[PDF]], [[TIFF]], etc) supported
** Network, USB, Parallel or other connection types
** Network print types available (Raw, [[Line_Printer_Daemon_protocol|LPR]], [[Internet_Printing_Protocol|IPP]], [[FTP]] printing, print via [[email]] etc)
* '''Output'''
** Printing speed (typically given in pages per minute or '''ppm''')
** Printer technology (e.g. [[Inkjet_Printer|InkJet]]/[[Laser_printer|Laser]]/Color Laser)
** Paper formats (what kind of paper sizes and stocks the MFP can output)
** Direct CD/DVD Label Printing (usually only available on some [[Inkjet_Printer|InkJet]] AIO models)
** Resolution [[Dots per inch|DPI]] - this is an important metric for both printing and scanning quality. (note that print DPI is rarely greater than 600dpi actual. Some MFPs use a system similar to sub-pixel rendering on computer displays to give "enhanced" resolutions of 1200x600 or 1800x600, however it is important to note that this is not a true resolution)
** [[Duplex printing]] capability - Whether the MFP can print on both sides of a sheet of paper without manual intervention by the user.
** Ability to print directly to the MFPs internal storage function
** Capability of using the MFPs finishing functions (see below under Copy features/functions)
===Scan features/functions===
* '''Input'''
** [[Automatic Document Feeder]] (ADF) - this allows multiple sheets of paper to be input without manually placing each piece of paper on the platen glass.
** [[Duplex scanning]] capability (depends on the ADF) - Whether the MFP can scan both ides of a sheet of paper without manual intervention by the user.
** Ability to retrieve a document from internal storage and send it as if it was a new "scan"
* '''Output'''
** Scan transfer methods available (e.g. [[FTP]], [[WebDAV]], [[Email]], [[Server_Message_Block|SMB]], [[Network_File_System_(protocol)|NFS]], [[TWAIN]])
** Scan file formats available (e.g. [[PDF]], [[TIFF]], [[JPEG]], [[XML_Paper_Specification|XPS]], etc)
** Security of scanned documents - such as PDF encryption, [[digital signature]]s and so on.
===Fax features/functions===
* [[Cordless telephone]] (generally only a consideration for AIO or smaller SOHO products)
* [[Answering machine]]
* Color Fax capability
* [[Transmission Control Protocol|TCP]]/[[Internet Protocol|IP]] Fax methods such as [[SIP Fax]] (Fax over IP), Network Fax (via [[SMTP]]), Internet Fax and so on
* PC Fax send and receive capability
===Copy features/functions===
* '''Document Finishing capabilities'''
** Duplex output
** Stapling
*** Single point
*** Two point
*** Staple positioning
** Holepunching
*** US holepunch or international
*** Number of holes (2/3/4)
** Folding
*** Half fold / crease
*** Fold and centre staple (for Booklet pagination)
*** Cover insertion for booklets
*** Cover binding (generally only available on production printing models) - differs from "cover insertion", in that a cover is physically bound to the book instead of simply placing it around the other pages. Cover binding often uses hot glue to bind the cover to the finished book.
*** Trimming for folded documents to avoid "creep"
*** Tri-fold / Envelope-folding
* '''Document editing modes'''
** n-in-one (2 in 1, 4 in 1 etc)
** Booklet pagination / "perfect binding" booklet pagination
** Page numbering / text & image stamping / watermarking
** Image scaling / rotation
* '''''Plus, see items under "Print features/functions" output and "Scan features/functions" input'''''
===Document storage features/functions===
* Documents storage capability the MFP
* Storage ([[Hard_disk_drive|HDD]]) capacity
* User authentication for the stored document, and any relationship to the user authentication of the MFP (e.g. Network authentication with a server or custom software, internal only, etc)
===Network features/functions===
* Wireless network capability
* [[Active Directory]] or other authentication functionality
* Data encryption
* [[IPv6]] support
* [[SNMP]] support - both private and public [[Management_Information_Base|MIB]] specifications
===Other features/functions===
* Software - Many MFPs support advanced functionality through third party software such as [[optical character recognition]]. In some cases, these software components are not specific to the MFP being used, however it is important to determine this, as in other cases proprietary technologies are used that effectively tie the software to the platform.
* [[SDK]] availability and licensing model
* User interface - By their nature, MFPs are complex devices. Many MFPs now include LCD screens and other user interface aids. Generally, AIO and SOHO products contain simple LCD displays, while Office MFPs contain advanced LCD panels resembling a custom computer-like user interface (some MFPs also offer optional keyboard and mouse attachments).
== Internal Architecture ==
=== Hardware ===
MFPs, like most external computer peripherals that are capable of functioning without the computer, are essentially a type of [[computer]] themselves. They contain [[RAM|memory]], one or more [[CPU|processors]], and often some kind of storage, such as a [[Hard Disk Drive]] or [[Flash memory]].
As mentioned in the Types of MFP section, the physical print engine may be based on several technologies, however most larger MFPs are an evolution of a digital [[photocopier]].
=== Software ===
MFPs also run a set of instructions, either in [[firmware]] or from their internal storage, which is comparable to a computer's [[Operating System]].
Generally, as the size and complexity of an MFP increases, the more like a computer the device becomes. It is uncommon for a small AIO or even a SOHO MFP to use a general purpose computer [[Operating System]], however many larger MFPs run GNU/[[Linux]]<ref name=C6500Linux>{{cite web | title = Konica Minolta C6500 Common Criteria Certification report, mentioning TimeSys Linux as the Image Control Program core OS | url = http://www.ipa.go.jp/security/jisec/jisec_e/documents/c0087_erpt.pdf | accessdate = 2008-03-20}}</ref> or [[VXWorks]]<ref name=VXWorks>{{cite web | title = List of WindRiver (VxWorks) customers, including several MFP manufacturers | url = http://www.windriver.com/portal/server.pt?space=Opener&parentname=CommunityPage&control=OpenObject&in_hi_OpenerMode=2&in_hi_ClassID=512&in_hi_ObjectID=715#consumer | accessdate = 2008-03-20}}</ref>.
Additionally, many [[print controller]]s, separate, but integral to the MFP, also run computer [[Operating System]]s, with GNU/[[Linux]]<ref name=EFILinux>{{cite web | title = EFI Antivirus guidelines for Linux based RIPs | url = http://www.efi.com/documents/support/security/security_antivirus_linux.pdf | accessdate = 2008-03-20}}</ref> and [[Microsoft Windows]] (often [[Windows NT 4.0 Embedded]], [[Windows XP Embedded]]<ref name=EFIXP>{{cite web | title = EFI Antivirus guidelines for Windows XP Embedded based RIPs | url = http://www.efi.com/documents/support/security/security_antivirusXP.pdf | accessdate = 2008-03-20}}</ref>) and even [[Mac OS X]]<ref name=SplashMac>{{cite web | title = Customer release notes for Splash G640 Color Server for Xerox DocuColor 12 Series | url = http://download.support.xerox.com/pub/docs/DocuColor_12CP/userdocs/any-os/en/Splash_G640_Color_Server_Cust_Rel_Notes.pdf | accessdate = 2008-03-20}}</ref> sometimes being used.
On top of the core [[Operating System]] or [[Firmware]], the MFP will also provide several functions, equivalent to [[Application_software|applications]] or in some cases [[Daemon_(computer_software)|daemons]]/[[Windows_service|services]] on a desktop computing platform.
These functions may include (amongst many others):
* MFP Panel control for user input
* [[Bytecode]] interpreters or [[Virtual Machine]]s for internally hosted third party applications
* [[Web server]] for remote management functions
* Network service [[Client_(computing)|clients]] for sending of documents to different destinations
* Network service [[Server_(computing)|servers]] for receiving documents for print or storage
* Image conversion and processing functions
* [[Raster image processing]] functions (although, often this task is handled by a separate [[print controller]] unit instead)
==Software==
Computer systems equipped with the proper software must be able to take advantage of the MFP's capabilities, an important requirement to research when considering integrating an MFP with an existing office. Some or all of the following functionality might be provided:
* Device administration and configuration
* Monitoring of print quotas, toner/ink levels etc.
* Document type/paper input mode selection
* [[document imaging|Document imaging]], such as ad hoc scanning
* [[document management system|Document management]] such as remote scanning, document type conversion from text to [[PDF]], [[Optical character recognition|OCR]], etc.
Software developers for MFPs include Captaris [http://www.captaris.com],[[Ecopy]], [[Nuance Communications|Nuance]], NSi, Paper River Consulting, [[Ringdale]] and Omtool.
==Software Development Kits==
In addition to specific software packages, many vendors also provide the ability for the user to develop software to communicate with the MFP through a [[Software Development Kit]]. Different vendors have different licensing models, from completely "closed" proprietary systems (often with large costs involved) to open strategies with no direct cost involved.
An incomplete list of these technologies is:
* [[Canon MEAP]] (Multifunctional Embedded Application Platform)
* [[Konica Minolta OpenAPI]]
* [[Sharp OSA]] (Open Systems Architecture)
* [[Xerox EIP]] (Extensible Interface Platform)
In general, these technologies fall in to one of two technical models - Server based, or MFP internal software.
Server based technologies use a method to communicate information to and from the MFP (often [[SOAP]]/[[XML]] based), running the operating code on a suitably powered computer on the network. This method has the advantage of being very flexible, in that the software is free to do anything that the developer can make the computer do. The only limit from the MFP itself is the capability of the MFP to display a user interface to the workings of the application. As many of the applications are based around custom printing, scanning and authentication requirements, the MFP manufacturers that use this method gravitate towards these core technologies in the user interface.
MFP internal software, by comparison, has the advantage of not requiring anything outside of the MFP. The software runs within the MFP itself and so even a complete network outage will not disrupt the software from working (unless of course the software requires a network connection for other reasons). MFP internal software is often, but not always, [[Java_(programming_language)|Java]] based and runs in a [[Java Virtual Machine]] within the MFP. The negative side to this kind of software is usually that it is much more limited in capabilities than Server based systems.
