Shows what functions that comes with the printer.

There are three varieties of printers: dot matrix (older technology, high volume, lesser printing quality), inkjets (high quality prints considering the price, with good colour print outs), laser printers (high quality and small cost per print out in black and white) and LED (Light Emitting Diode). It is usual to find inkjet printers at home while LED/laser printers are more common in the office. Dot matrix printers are excellent for label writing or when the printer has to "hit through" double copies, for example carbon paper.

Today it is possible to find colour printers that print to a very high quality.

Normally the printer can print out on traditional A4 paper but some can handle A2 printouts. A2 is a considerably bigger format than A4.

A local area network that transmits over the air typically in the 2.4GHz or 5GHz unlicensed frequency band. It does not require line of sight between sender and receiver. Wireless base stations (access points) are wired to an Ethernet network and transmit a radio frequency over an area of several hundred feet through walls and other non-metal barriers. Roaming users can be handed off from one access point to another like a cellular phone system.

The major wireless LAN standard today is the IEEE 802.11, more widely known by the "Wi-Fi" logo. 802.11 a, b, g and n are different standards which limit the maximum data transfer speed. Wireless Wi-Fi adapters (Wi-Fi transceivers) are either built into most new laptops or added via a PC card slot or USB. Wireless adapters for desktop machines can be plugged into a USB port or PCI slot.

The speed of the printer when printing in black, measured in pages per minute.

Enables printing on both sides of a sheet of paper. Optional means that you have to buy a add-on to make duplex printing available.Shows if the printer can print on both sides of the paper. Optional means it needs a add-on to make duplex printing available.

This is the maximum resolution you can choose when youre going to print out.

This shows if the printer has a built in fax machine.

This is what types of connections that comes with the printer. Ethernet is if printer has a built in network card. USB is for connecting printer a USB unit trough a regular USB cable. PictBridge is special connection for digital cameras to be connected directly to the printer for printing out your pictures that is stored in cameras memory, this connection also uses a USB cable but is called PictBridge.

Indicates if the printer can be connected to a network either through a built in network card or if it says "Yes Optional" means it has a slot for future addition of a network card (Ethernet).
