Description of copying function (colour or monochrome).

The greatest amount of detail that can be produced by a copy of a document.

To convert a document or picture into digital form for storage or processing on a computer, by scanning it using a scanner.

How many pixels a scanner can see. Most commonly, this is measured in dots per inch (dpi).For example, a typical flatbed scanner will use a scanning head with 300 sensors per inch, so it can sample 300 dots per inch (dpi) in one direction. To scan in the other direction, it will move the scanning head along the page, stopping 300 times per inch, so it can scan 300 dpi in the other direction as well. This scanner would have an optical resolution of 300 x 300 dpi. Some manufacturers stop the scanning head more frequently as it moves down the page, so their machines have resolutions of 300 x 600 dpi or 300x1200 dpi.

The maximum number of prints/copies made by a printer/copier in a fixed period.

Device similar to a scanner which converts paper documents into digital information for emailing, archiving, document management and more.

The amount of print cartridges. A print cartridge is a container holding a quantity of ink which is inserted into a inkjet printer mechanism.

The colours that can be produced by the printer.

The maximum paper size the device can handle, defined by ISO A-series.

Different sizes of paper from A0 (big) to A9 (small). A4 is the most common size used for printing documents.

Most common industry-standard communication protocols ranging from RS-232, RS-422, RS-423, RS-485, and LVDS to USB.

With direct printing it is possible to print your photographs or other documents directly to a printer from a compatible device, without the use of a computer.

The device features a socket into which a USB cable can be plugged.

Popular technology that allows an electronic device to exchange data or connect to the internet wirelessly using radio waves.

An Ethernet LAN (Local Area Network) interface is present, for a wired conection via a cable.

The type of wireless local area network (LAN): ad-hoc (where units in a network communicate peer-to-peer) or Infrastructure (units communicate with each other via an access point). A LAN interconnects computers in a small area e.g. home, school or office.

Bluetooth is a low-power radio technology developed to replace the cables and wires currently used to link or connect electronic devices such as personal computers, printers, and a wide variety of handheld devices including mobile phones. Because it uses radio-wave connectivity, a Bluetooth-enabled device has a constant, established connection to whatever browser it uses. This saves the user the trouble of logging on to check for emails or news updates, for example.

Apps etc. which allow users to send a print job from a smartphone or tablet to a printer via a wireless network.

The maximum amount of memory inside a product, usually measured in bytes e.g megabytes (MB) or gigabytes (GB).

The device includes a card reader e.g. a card reader in the disk bay of a computer or thin client to permit log-on using smart/pin cards.

The amount of memory, usually measured in bytes (e.g. MB, GB), which is installed in the system's hardware.

Whether or not a processor is built into the device.

The clock rate is the fundamental rate in cycles per second (measured in hertz) at which a computer performs its most basic operations such as adding two numbers. There are more factors, like internal memory size, that influence a computer's actual response time.

The colour e.g. red, blue, green, black, white.
