An ink cartridge or inkjet cartridge is a component of an inkjet printer that contains the ink that is deposited onto paper during printing.

Each ink cartridge contains one or more ink reservoirs; certain producers also add electronic contacts and a chip that communicates with the printer.

Thermal

Most consumer inkjet printers, such as those made by Canon, HP, and Lexmark (but not Epson) use a thermal inkjet; inside each partition of the ink reservoir is a heating element with a tiny metal plate or resistor. In response to a signal given by the printer, a tiny current flows through the metal or resistor making it warm, and the ink in contact with the heated resistor is vaporized into a tiny steam bubble inside the nozzle. As a consequence, an ink droplet is forced out of the cartridge nozzle onto the paper. This process takes a fraction of a millisecond.

The printing depends on the smooth flow of ink, which can be hindered if the ink begins to dry at the print head, as can happen when an ink level becomes low. Dried ink can be cleaned from a cartridge print head using isopropyl alcohol or water. Isopropyl alcohol will damage the printing head, melting the plastic at the connections and rubber gaskets. Tap water contains contaminants that may clog the print head, so distilled water and a lint-free cloth is recommended.

The ink also acts as a coolant to protect the metal-plate heating elements − when the ink supply is depleted, and printing is attempted, the heating elements in thermal cartridges often burn out, permanently damaging the print head. When the ink first begins to run low, the cartridge should be refilled or replaced, to avoid overheating damage to the print head.

Piezoelectric

All Epson printers use a piezoelectric crystal in each nozzle instead of a heating element. When current is applied, the crystal changes shape or size, increasing the pressure in the ink channel and thus forcing a droplet of ink from the nozzle. There are two types of crystals used: those that elongate when subjected to electricity or bi-morphs which bend. The ink channels in a piezoelectric ink jet print head can be formed using a variety of techniques, but one common method is lamination of a stack of metal plates, each of which includes precision micro-fabricated features of various shapes (i.e. containing an ink channel, orifice, reservoir and crystal). This cool environment allows use of inks which react badly when heated. For example, roughly 1/1000th of every ink jet is vaporised due to the intense heat, and ink must be designed not the clog the printer with the products of thermal decomposition. It also can make a smaller ink drop in some situations than thermal inkjet schemes.

A virtual private network (VPN) extends a private network across a public network, such as the Internet. It enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network, and thus are benefiting from the functionality, security and management policies of the private network. A VPN is created by establishing a virtual point-to-point connection through the use of dedicated connections, virtual tunnelling protocols, or traffic encryption.

VPNs cannot make online connections completely anonymous, but they can usually increase privacy and security. To prevent disclosure of private information, VPNs typically allow only authenticated remote access using tunnelling protocols and encryption techniques.

The VPN security model provides:

Confidentiality such that even if the network traffic is sniffed at the packet level,
an attacker would only see encrypted data

Sender authentication to prevent unauthorized users from accessing the VPN

Message integrity to detect any instances of tampering with transmitted messages
