Orange Pi: It is a single-board open source computer, based on Raspberry Pi1 but lower priced and manufactured by Shenzhen Xunlong Software CO., Limited.

Raspberry Pi: it is a credit card size computer that connects to your TV and a keyboard. The plate, which used to be smaller than a credit card, has several ports and inputs, two USD, one Ethernet and an HDMI output.

It is a board based on an ATMEL microcontroller. The microcontrollers are integrated circuits in which you can record instructions, which you write with the programming language that you can use in the Arduino IDE environment.

A reduced plate computer or computer board (in English: Single Board Computer or SBC) is a complete computer in a single circuit.

Continuous ink system has many advantages that have made it popular in many countries around the world: The cost of ink is reduced, compared to the continuous replacement of cartridges, it has little maintenance (only in the case that the cartridge is damaged, it must be do a deep maintenance)

Cartridges: It is a replaceable set of a printer that contains the ink and, frequently, also the own printhead that projects the ink on the paper during printing.

Toner: Also called dry ink by functional analogy with ink, it is a fine powder, usually black in color, which is deposited on the paper to be printed by means of electrostatic attraction or magnetography.

Laser printer: The printing device consists of a photoconductive drum attached to a toner deposit and a laser beam that is modulated and projected through a specular disc towards the photoconducting drum.

Thermal printer: This paper is impregnated with a waxy substance that reacts to heat and usually turns black. The paper is normally purchased in rolls, the standard width being 40 mm, although there are also 50 and 80 mm, such as thermal printers of ATMs.
