An MFP (Multi-Function Product/ Printer/ Peripheral), multi-functional, all-in-one (AIO), or Multi-Function 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 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: E-mail, Fax, Photocopier, Printer, Scanner.

MFP manufacturers traditionally divided MFPs into various segments. The segments roughly divided the MFPs according to their speed in pages-per-minute (ppm) and duty-cycle/robustness. However, many manufacturers are beginning to avoid the segment definition for their products, as speed and basic functionality alone do not always differentiate the many features that the devices include. Two color MFPs of a similar speed may end 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 avoids the segment definition.

Many MFP types, regardless of the category they fall into, also come in a "printer only" variety, which is the same model without the scanner unit included. This can even occur with devices where the scanner unit physically appears highly integrated into the product.

As of 2013, almost all printer manufacturers offer multifunction printers. They are designed for home, small business, enterprise and commercial use. Naturally, the cost, usability, robustness, throughput, output quality, etc. all vary with the various use cases. However, they all generally do the same functions; Print, Scan, Fax, and Photocopy. In the commercial/enterprise area, most MFP have used laser-printer technology, while the personal, SOHO environments, utilize inkjet methods. Typically, inkjet printers have struggled with delivering the performance and color-saturation demanded by enterprise/large business use.[1] However, HP has recently launched a business-grade MFP using inkjet technology.

In any case, instead of rigidly defined segments based on speed, more general definitions based on intended target audience and capabilities are becoming much more common as of 2013. While the sector lacks formal definitions, it is common agreed amongst MFP manufacturers that the products fall roughly into the following categories:

All-in-one

An All-in-one is a small desktop unit, designed for home or home-office use.

These devices 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 All-in-one will always include the basic functions of Print and Scan, with most also including Copy functionality and a lesser number with Fax capabilities.

In the past, these devices were usually not networked, and were generally connected by USB or Parallel. As of 2013 even inexpensive all-in-one devices support ethernet and/or wi-fi connections. In some cases the wireless devices require connection to a host computer by wire (usually USB) to initialize the device, and once initial setup is done, support wireless operations for all the work performed thereafter.

All-in-one devices may have features oriented to home and personal use that are not found in larger devices. These functions include smart-card readers, direct connection to digital cameras (e.g. PictBridge technology) and other similar uses.

The print engine of most All-in-one devices is based either on a home desktop inkjet printer, or on a home desktop laser printer. They may be black-and-white or colour capable. Laser models provide a better result for text while inkjet gives a more convincing result for images and they are a cheaper multifuncional.[2]

Some of these devices, like the Hewlett-Packard Photosmart C8180 printer, have a DVD burner and Lightscribe functionality where the user could burn DVDs and create an image on a special Lightscribe DVD or CD using special software like Roxio or Nero AG Software Suite to create the image. To create a Lightscribe image takes about 10 to 25 minutes.

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.

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 hole-punching, however this is rare. In general, document output offset, sorting and collation are standard capabilities.

By comparison to an All-in-one product, 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 photocopiers, and the print engine is accordingly based around this type of technology.

Office MFP

A mid-sized free-standing 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, SMB and 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 parallel connections. Most Office MFPs have their history in mid-range photocopiers (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 free-standing 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 into "light" production printing and "heavy" production printing, with the differentiating factor being the speed. A 100ppm device for example, falls into 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 into 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):

Internal architecture

Hardware

MFPs, like most external peripherals that are capable of functioning without a computer, are essentially a type of computer themselves. They contain memory, one or more processors, and often some kind of local 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.

Security

When disposing of old printers with local storage, one should keep in mind that confidential documents (print, scan, copy jobs) are potentially still unencrypted on the printer's local storage and can be undeleted.[3]

Software

MFPs also run a set of instructions 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 operating system, however many larger MFPs run Linux[4] or VxWorks.[5]

Additionally, many print controllers, separate, but integral to the MFP, also run computer operating systems, with GNU/Linux[6] and Microsoft Windows (often Windows NT 4.0 Embedded, Windows XP Embedded[7]).

On top of the core operating system and firmware, the MFP will also provide several functions, equivalent to applications or in some cases daemons or services.

These functions may include (amongst many others):

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:

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:

In general, these technologies fall into 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 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.

Manufacturers

MFP manufacturers/brands include

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.
